ac4c11b5e9 fix(storage): move the app->location index out of configs/
Follow-up to 928e244, which stopped configs/ subdirectories being sourced
without a .category marker. That closed the hole; this removes the thing
that fell into it.

storageIndexFile pointed at configs/storage/app_locations. The file's
requirements are only "manager-owned" and "not on a removable disk" —
configs/ satisfies both, which is why I put it there, and it was still
wrong: that tree carries a third property the file violates. sourceScanFiles
SOURCES what it finds under configs/, and sourcing means executing.

The index is a TSV of "<slug><TAB><root>", which bash reads as a command
and its argument. Harmless while no slug matched a real executable. The
row for the app named `libreportal` armed it, because that IS the CLI on
PATH: sourcing ran `libreportal /libreportal-containers`, which re-entered
the scan, which sourced the file again — one process pair per level until
the host OOMed and took the desktop session with it.

It now lives at $system_dir/storage/app_locations, with a one-shot
migration so an install that already has an index keeps knowing where its
apps live rather than silently forgetting. libreportal-ownership
reconciles the new directory, and scan_files.sh gained a note that
configs/storage/ carries no .category on purpose.

scripts/dev/lp-configs-guard-test covers both ends: the index never lands
in configs/, a legacy one migrates, and a file of the exact detonating
shape placed in an unmarked configs/ subdirectory is not executed while a
marked category still loads.

Also wires sourceStorageLocations into the config scan beside
sourceBackupLocations — per-location configs sit at depth 3, below the
generic scan, and need their own walker like the backup ones do.

2d24a764a8 refactor(storage): route elevation tests and the WebUI tree through paths.sh
Two mechanical sweeps, no behaviour change on a single-root install.

The 14 `[[ "$p" == "$containers_dir"* ]]` prefix tests that decide
manager-vs-container-user elevation become pathIsContainerData, so a file
on a second storage root is no longer misclassified as manager-owned —
which would have written it with the wrong owner and failed later, far
from the cause. The 65 references to the WebUI's own tree become
webuiDir(), which is pinned to the primary root by design.

Two traps found while doing it:

run_privileged.sh is sourced directly by init.sh without paths.sh, so it
needs a fallback. Defining one named pathIsContainerData was wrong:
generate_function_manifest.sh indexes top-level definitions, and the
resulting autoload stub would have shadowed the real multi-root
implementation with the primary-only fallback — silently classifying
every file on a second disk as manager-owned, which is exactly the bug
this sweep exists to prevent. Renamed to _runCfgIsContainerPath, which
delegates when the real one is loaded.

setup_lock.sh built its path in a top-level assignment, so it was
evaluated at source time and needed the file flagged eager. Made it a
function instead: the path resolves on call, and the file drops off
LP_EAGER_FILES entirely.

7aed9102c4 fix(tools): keep the user on the Tools tab and show the result there
Running any tool jumped to the Tasks tab and left the user stranded there. That
is right for an install — long, log-heavy, worth watching — and wrong for a
tool, which is a short admin action whose answer is one line. Worse, half of
these are only meaningful back on Tools: List Users opens a modal over that tab,
and Create User Account returns a generated password that was being buried in a
log the user then had to go read.

Tools now stay put. On completion the tool's own outcome lines — the
isSuccessful/isError/isNotice output, ANSI stripped and framework boilerplate
filtered — are shown in a small result modal, with a View log button for
anything needing the full detail. list_users is left alone because the existing
account-list modal is already a better result view.

Also stops generate_arrays.sh walking scripts/dev. That directory is
`export-ignore`d, so it exists in a working clone but never in a shipped
install; generating a files_dev.sh entry from it wrote a reference into
files_source.sh that no install could satisfy, and the loader treats a missing
array file as a broken installation — every libreportal command stopped with
"files_dev.sh is missing from your LibrePortal Installation". Excluded alongside
unused/, system/ and release/. Regenerating also picked up scripts/validation,
which had never had an array file.

And Matrix's account listing prints its aligned line from python rather than
re-splitting the marker line in bash: TAB is IFS whitespace, so an empty display
name collapsed into the previous delimiter and shifted every later column.

48cb5d9380 fix(backup): name preserved env vars instead of relying on sudo -E
sudo-rs — the default sudo from Ubuntu 25.10, so on 26.04 — does not
implement bare -E. It does not reject it either: it warns to stderr
("preserving the entire environment is not supported, '-E' is ignored")
and runs the command with the environment DROPPED, leaving the exit
status untouched. Callers capture stderr, so the warning is invisible and
the backup engines simply never receive RESTIC_PASSWORD / BORG_PASSPHRASE
/ KOPIA_PASSWORD and cannot open the repository.

Name the nine vars explicitly via --preserve-env=<list>, which sudo-rs
and classic sudo (>=1.8.21, so Debian 10's 1.8.27) both honour, so this
needs no version gate. The list is cross-checked against every
RESTIC_/BORG_/KOPIA_ var the engine env scripts export.

The list lives in variables.sh with a literal fallback in runBackupOp,
because init.sh sources run_privileged.sh directly during install without
ever loading variables.sh — an unguarded empty list would silently
reproduce the same dropped-credential bug.

restoreFirstRunDiscover now goes through runBackupOp rather than issuing
its own sudo. It was the only backup-engine call bypassing that funnel,
which is why it missed this fix by construction; routing it back also
gives it the -H that keeps restic's cache under the backup user's HOME.

a27304a191 fix(distribution): harden the artifact apply pipeline (adversarial review)
A 4-lens adversarial security review of the Phase 2 applier raised 19 issues
and confirmed 17 after per-finding verification. All are trust-boundary (they
require the signing key), but several break the explicit "no code-exec, always
reversible, nothing-silent" contract, so all 17 are fixed:

Trust path — fail CLOSED, never misreport:
- lpFetchIndex now surfaces the real signature state (LP_INDEX_SIGSTATE);
  artifactApply REFUSES to mutate unless the index is actually verified, and
  _artifactFetchPayload refuses an unsigned payload. The read path still
  tolerates dev/unsigned but now says "UNSIGNED" instead of "Signed + verified".
- valid_until and index_serial are now MANDATORY + numeric in lpFetchIndex
  (missing = refuse) — closes the anti-withholding / anti-rollback fail-opens.

Injection / code-exec (defense in depth even for a signed payload):
- runFileWrite rootless branch no longer builds a `bash -c` shell string with the
  destination interpolated — it uses the argv form (like runFileOp), so a path
  with a quote can't inject a command as the install user. (shared-helper fix)
- op paths must match a safe-filename charset (no quotes/$/backtick/;/newline);
  set-config-key values and set-compose-image refs are charset-guarded too.
- content_b64 is validated as real base64 at precheck.

Reversibility / honest failure:
- dockerComposeUp now returns the real compose exit status (it always returned 0,
  so the updater's rollback gate AND the apply's start-failure detection were
  fail-open). (shared-helper fix)
- set-config-key undo captures the WHOLE config file (lossless) instead of a
  lossy re-parsed scalar; edit-only (rejects an absent key).
- _artifactReplayUndoFile returns non-zero if any inverse op fails; auto-rollback
  and revert now record "rollback-incomplete"/"revert-incomplete" + isError
  instead of falsely claiming success, and revert keeps the record for retry.
- applied-record write failure is checked — apply rolls back rather than leave an
  un-revertable change. System-scope regen failure is no longer swallowed.
- Writes are path-aware (configs/ -> runInstallWrite, container tree ->
  runFileWrite) so system-scope hotfixes write/restore correctly.
- Checked lazy-sourcing surfaces a clear error instead of a bare exit 127.

Unit-tested 35/35 (adds: command-sub value rejection, bad image-ref, invalid
base64, quote/metachar path-injection rejection, replay-failure reporting).

6089eb0882 fix(de-sudo): route container-tree writes through the privileged path
Two more cases of the manager writing directly into the container-owned
/libreportal-containers tree (same class as the regen-poll stamp), both masked
by a '✓ Success' that printed anyway:

- Password replacers (config/password/*): used 'runInstallOp sed -i' (manager)
  on app configs copied into the container tree, so sed -i EACCES'd its temp
  file and the substitution silently failed — the adguard.config 'couldn't open
  temporary file', leaving the literal RANDOMIZEDPASSWORD placeholder. Added
  runCfgOp (picks runFileOp vs runInstallOp by the target file's location) and
  routed every $file grep/sed/awk through it: password, username, hex, vapid,
  appkey, and bcrypt.

- Updater generator (webui_updater_scan): 'runFileOp cp <manager-tmp>' can't
  read the manager's 0600 mktemp as the container user, so it fell through to a
  manager 'cp' that EACCES'd on the container-owned out_dir. Switched the three
  writes to 'runFileWrite < tmp' (manager shell reads the tmp; container user
  tees the write).

Both deploy via the normal quick path (relocatable scripts) — no footprint bump,
no reinstall.

7513a62fde feat(crowdsec): migrate host-install to a dedicated libreportal-crowdsec helper
CrowdSec's host-side install (the agent + nftables bouncer the LibrePortal
Traefik plugin talks to) had stayed on blanket sudo throughout the rootless +
de-sudo hardening: `sudo apt-get install crowdsec`, `curl | sudo bash`,
`sudo sed -i /etc/crowdsec/config.yaml`, `sudo touch + sudo chmod /var/log/
crowdsec*.log`, `echo $key | sudo tee /etc/crowdsec/traefik_bouncer.key`,
plus `sudo cscli capi register / console enroll / bouncers add`. None of
those are in the scoped LP_HELPERS / LP_SYSTEM sudoers grant the manager
now holds, so any user who enabled crowdsec would have hit hard sudo
failures on every privileged step.

Follow the libreportal-appcfg / libreportal-bininstall pattern: one new
root-owned helper at /usr/local/lib/libreportal/libreportal-crowdsec
that does every privileged op behind a fixed action vocabulary with strict
argument validation. The manager calls in via runCrowdsec — the scoped
sudoers grants exactly one binary, the same trust boundary the other
helpers rely on.

Actions:
  install               apt repo + agent + firewall-bouncer + enable +
                        crowdsecurity/{linux,sshd} collections + reload
                        (idempotent — skips parts already in place)
  services <verb>       enable | disable | restart
  capi <verb>           register | unregister | status
  console <verb>        enroll <token> | disenroll | status
                        token format strictly validated
  bouncer-traefik-init  cscli register + write the manager-owned key file
                        atomically (returns EXISTS or GENERATED:<key>)
  bouncer-priority      bouncer yaml nftables priority → -100
                        (moved from libreportal-appcfg; one helper for
                        every crowdsec root op)
  bind-lapi             flip listen_uri to 0.0.0.0:8080 in config.yaml
  prometheus <on…|off>  flip the prometheus block (validated addr/port)
  touch-host-logs       create + chmod 0644 /var/log/crowdsec*.log so the
                        libreportal container can tail them

Wired in via:
  - new sudoers Cmnd_Alias entry for the helper in LP_HELPERS
  - new helper baked alongside the others by initRootHelpers
    (replaces __SYSTEM_DIR__ / __CONTAINERS_DIR__ / __MANAGER__ at
    install, with safe runtime fallbacks if unbaked)
  - new runCrowdsec dispatch in scripts/docker/command/run_privileged.sh

containers/crowdsec/scripts/crowdsec_install_host.sh now drives the whole
flow through runCrowdsec — every `sudo …` is gone, the compose-toggle sed
uses runFileOp, and the security_crowdsec CFG mirror uses runInstallOp
(configs/ is manager-owned). Net: install script shrinks ~80 lines while
gaining a single auditable trust boundary. crowdsec_fix_priority.sh swung
over to runCrowdsec bouncer-priority too — the appcfg crowdsec_priority
action drops out cleanly.

18e692ffbb fix(backup): reset HOME when dropping to the backup user in runBackupOp
runBackupOp dropped privileges to $docker_install_user with `sudo -E`,
which preserves the CALLER's environment — including HOME. The caller is
the manager (libreportal), so restic-running-as-dockerinstall ended up
with HOME=/home/libreportal and tried to mkdir
`/home/libreportal/.cache/restic` for its cache. dockerinstall can't
write into libreportal's home, so every backup ran with:

    unable to open cache: mkdir /home/libreportal/.cache/restic: permission denied

twice (once in backup, once in the verify-via-scratch-restore step), with
restic falling back to a no-cache run that's a few × slower than it
should be.

Add `-H` (sudo's "reset HOME to target user's home"). Now restic sees
HOME=/home/dockerinstall, creates ~/.cache/restic there (dockerinstall
owns its own home, no help needed), and the warning is gone. Confirmed
live: a `backup app create linkding` round-trip is silent on cache, and
the dir lands at /home/dockerinstall/.cache/restic, mode 0700, correctly
owned.

All restic/borg/kopia calls funnel through runBackupOp, so this single
character fix covers every backup-tool invocation.

e4872ab511 refactor(paths): single source of truth for a relocatable, split layout (phase 1)
Introduce scripts/source/paths.sh as the canonical path resolver for three
independently-relocatable roots:
  LP_SYSTEM_DIR      manager-owned control plane (configs/logs/install/db/ssl/ssh/migrate)
  LP_CONTAINERS_DIR  container-user-owned live app data
  LP_BACKUPS_DIR     container-user-owned backup repos (own mount-able)

Roots come from the environment when set (install bakes them; CLI/app inherit
from init.sh), else default to /libreportal-*. A transitional compat default
keeps EXISTING installs (legacy single /docker tree, by config marker) on /docker
until a deliberate reinstall, so deploying this never strands a running box.

- init.sh derives the same vars inline (self-contained for the bare /root/init.sh
  reinstall case); paths.sh mirrors it for the standalone task/check processors,
  which now self-locate their scripts dir and source it.
- Replace functional /docker literals with the derived vars across runtime,
  install, backup, crontab, crowdsec/restic, headscale, and reinstall paths;
  clean the inert '== /docker/containers/*' guard fallbacks to the variable form.
- backend: CONTAINERS_DIR now from LP_CONTAINERS_DIR (compose env, filled at
  generation via a new CONTAINERS_DIR_TAG), legacy-safe default for un-recreated
  containers.
- backup default path falls back to the backups root; exclude paths.sh from the
  sourced-file arrays (bootstrap file, sourced explicitly).

The CLI-wrapper heredoc + root helpers still reference /docker; those get baked
in phase 3. No layout/ownership change yet (phase 2).

15fc42c858 refactor(layout): consolidate out-of-/docker files + fix sysctl dir
Organise the system footprint outside /docker:
- All LibrePortal executables now live together in /usr/local/lib/libreportal/
  (root:root): the 7 root helpers AND the CLI wrapper. /usr/local/bin/libreportal
  becomes a symlink onto $PATH. run_privileged._runRootHelper, init.sh
  (initRootHelpers + scoped-sudoers Cmnd_Alias + command setup) all point there.
  The wrapper is now root-owned too (manager can't tamper with its entrypoint).
- Fix a real bug: rootless sysctl settings were written to /etc/sysctl/99-custom.conf,
  a dir  does NOT read, so net.ipv4.ip_unprivileged_port_start /
  kernel.unprivileged_userns_clone never persisted across reboot. Moved to
  /etc/sysctl.d/99-libreportal-rootless.conf (the existing
  reload now actually applies them). Consistent libreportal* naming.
- Drop dead fqdn_file=/root/libreportal-fqdn.txt global (never used).
- Add FOOTPRINT.md: a manifest of every file LibrePortal places outside /docker
  (doubles as an uninstall checklist).

cd4fd55a6d feat(desudo): helper-ize backup-engine + app-config installs; retire standalone WireGuard
Bring the remaining deferred subsystems under the scoped sudoers, and drop
the one that's redundant.

Backup engines + app configs -> root-owned helpers (same pattern as
ownership/dns/ssh/socket/svc):
- scripts/system/libreportal-bininstall: install <restic|kopia> — does the
  whole pkg-manager/signed-download install itself for a fixed, validated
  engine name (no blanket sudo apt-get/install). restic_install/kopia_install
  call it.
- scripts/system/libreportal-appcfg: {adguard-auth <user> <bcrypt>|
  crowdsec-priority|owncloud-config <public> <host> <ip> <public_ip>} —
  faithful ports of the AdGuard yaml / CrowdSec bouncer / ownCloud config.php
  rewrites, fixed paths + validated args. adguard_auth/crowdsec_fix_priority/
  owncloud_setup_config call it.
- run_privileged: runBinInstall / runAppCfg; init.sh installs + allowlists both.

Retire standalone (host-level) WireGuard — it's a duplicate of the
containerized containers/wireguard app (+ headscale mesh), its slirp4netns
speed rationale is largely moot with a better rootless net backend / typical
WAN-bound throughput, and it was the heaviest host-root subsystem (apt +
sysctl + iptables + /etc/wireguard), the worst fit for the rootless/
least-privilege direction:
- moved scripts/wireguard/ + manage_wireguard.sh + check_wireguard.sh to
  scripts/unused/; dropped the install-path call, the Tools menu 'w' entry,
  and the requirement check; removed the half-built libreportal-wg helper.
- generate_arrays.sh now also skips system/ (root-owned helpers, never
  sourced); arrays regenerated (files_wireguard.sh pruned).

9af2465ffe feat(desudo): socket + systemd-svc helpers; route traefik/db chowns + svc

sudoers:

- scripts/system/libreportal-socket: {rootless|rooted} {on|off} chmod of

  exit 3 = absent so the *_found flags come from its exit code)
- scripts/system/libreportal-svc: GENERATES + installs the systemd unit
  from config (mode/uid/baked manager) — never accepts unit content from
  the caller (arbitrary unit = root). Idempotent install/enable/restart.
- ownership helper: add db-own + app-file <app> <relpath> actions
- run_privileged: runSocket / runSvc
- set_socket_permissions -> runSocket; webui_install_systemd -> runSvc
  (+ crontab cleanup runs as the manager directly, no sudo -u self)
- before_start: db chown -> runOwnership db-own; traefik cert/yml ->
  runOwnership app-file (retires updateFileOwnership/changeRootOwnedFile)
- init.sh installs all five helpers

sudo sed/tee/cp on /etc (which is root-equivalent — sudo arg wildcards

  only, validates the IP argument
- scripts/system/libreportal-ssh-access: authorized_keys + sshd
  PasswordAuthentication management, with the lockout guards moved INTO the
  helper (the trust boundary) so a compromised manager can't bypass them
- run_privileged: _runRootHelper dispatcher + runResolv / runSshAccess
  (runOwnership now uses it too)
- init.sh: initRootHelpers installs all three helpers root:root 0755 with
  the manager name baked in
- setup_dns -> runResolv (+ ping de-sudo'd, works unprivileged); host_access

46622cd2f9 feat(desudo): root-owned ownership helper (no blanket sudo chown needed)
Under Model A the runtime runs as the manager, so establishing the
/docker ownership model needs root. Granting the manager a blanket
'sudo chown'/'sudo chmod' in the scoped sudoers would be root-equivalent
(chown /etc/sudoers, ...). Introduce a self-contained, root-owned helper
that performs only a FIXED set of reconciles on FIXED LibrePortal paths,
with owners derived from config + a baked manager name (never the caller)
and a strictly-validated app-name argument.

- scripts/system/libreportal-ownership: the helper (actions: reconcile,
  traversal, containers-top, app-perms, webui, taskdir, app-data-nobody)
- run_privileged: runOwnership wrapper (sudo the installed helper; run the
  bundled copy directly when already root mid-install)
- init.sh: installOwnershipHelper bakes the manager name and installs it
  root:root 0755 to /usr/local/sbin (manager can't modify it)
- libreportal_folders/app_folder/app_update_specifics/task processor:
  delegate the ownership chowns to runOwnership instead of runSystem chown

This removes chown/chmod-on-/docker from the runtime sudo surface, a
prerequisite for a non-root-equivalent scoped sudoers.

0b27ed1072 refactor(desudo): funnel backup-engine privilege drop through runBackupOp
The borg/restic/kopia engines all dropped to the dedicated backup user
via scattered 'sudo -E -u $docker_install_user'. Centralize that into a
single runBackupOp helper so the backup subsystem has one audit point and
the scoped sudoers needs only the (dockerinstall) drop rule.

Also:
- owncloud config heredoc tees -> runSystem (container-UID file)
- webui_display_logins: fix the broken 'command -v sudo sqlite3' guard
  to 'command -v sqlite3' (body already runs sqlite3 via runInstallOp)

10af56b9c4 refactor(desudo): rooted ops run as the manager user, not sudo->root
Maintainer confirmed the intended model: the manager user (libreportal, in the
docker group) owns /docker in BOTH modes and runs things directly; root:root was
always an accident of un-de-sudo'd sudo. Rework the helpers accordingly:

- add runAsManager (run as the manager: plain when already it at runtime, else
  sudo -u at install time) so files end up manager-owned, never root-owned.
- runFileOp/runFileWrite: rooted -> runAsManager (was sudo->root); rootless
  unchanged (docker install user owns containers/).
- runInstallOp/runInstallWrite: always runAsManager (control plane is manager-
  owned in both modes).
- runSystem unchanged (genuine root: apt/systemctl/ufw/sysctl).
All ~40 converted call sites inherit this via the helpers. reconcile's WebUI dir
now -> manager in rooted / docker install user in rootless.

68110d199c fix(rootless): slirp4netns default, manager-vs-container helper split, sysctl path
Reinstall test on Debian 12 surfaced three rootless-only breakages (rooted
was byte-identical/fine):

1. pasta blocked by Debian's passt AppArmor profile (DENIED ptrace read ->
   can't open container netns -> rootless dockerd never starts). Default
   CFG_ROOTLESS_NET back to slirp4netns (reliable); pasta stays selectable
   for hosts that relax the profile.
2. de-sudo mis-assigned helpers by owner. /docker management layer (apps DB
   chowned to libreportal by install_sqlite, /docker/logs) is MANAGER-owned,
   not dockerinstall. Add runInstallWrite; move apps-DB sqlite3 -> runInstallOp
   and /docker/logs appends -> runInstallWrite. Revert ownership-SETUP scripts
   (libreportal_folders, app_folder) to runSystem — they must run as root to
   establish ownership during install. Container files (/docker/containers/<app>)
   stay runFileOp.
3. kernel hardening sysctls written to /etc/sysctl/99-custom.conf, which
   'sysctl --system' does not read -> never applied. Write them to
   /etc/sysctl.d/99-libreportal-hardening.conf instead.

0c719b5912 harden(desudo): add runInstallOp helper + convert adguard/traefik/crowdsec/dashy
- New runInstallOp helper for manager install-dir/template ops (rooted:
  sudo; rootless: run as the current manager user, which owns the tree).
- adguard.sh, traefik.sh: container-config sed -> runFileOp.
- crowdsec.sh: host crowdsec systemctl/apt-get -> runSystem.
- dashy_update_conf.sh: conf-file mkdir/chown/md5sum/tee -> runFileOp/
  runFileWrite; docker ps/restart -> dockerCommandRun.
Deferred (cross-owner copy / temp-file across /tmp<->/docker, need rootless
env to bridge correctly): owncloud_setup_config.sh, adguard_auth.sh.

bdd73b4686 harden(desudo): append-capable runFileWrite + convert config-to-container
Add -a/--append to runFileWrite so the pervasive /docker/logs log-append
idiom (`… | sudo tee -a $logs_dir/$docker_log_file`) routes through the
mode-aware helper instead of raw sudo.

Convert scripts/config/docker/docker_config_to_container.sh fully: all
ops target /docker app config + logs (data-plane), so md5sum/grep/chmod/
cmp/editor -> runFileOp and the log-appends -> runFileWrite -a.
Byte-identical in rooted.

82839abea6 harden(desudo): arg-safe runFileOp + convert DNS subsystem off raw sudo
Give dockerCommandRunInstallUser an --argv mode that execs arguments
verbatim (sudo -u <user> env ... "$@") instead of bash -c "$*", and
point runFileOp at it. The old $*+bash -c re-parse silently mangled
backslashes/quotes in args — e.g. sed scripts (\1, \( become 1, ( ) and
the sqlite3 .backup arg — so rootless data-plane ops with regex were
broken. Verified: the WG_DEFAULT_DNS sed now applies correctly as the
install user. All existing runFileOp callers pass plain commands, so the
switch is safe (and fixes the latent sqlite3 case).

Convert scripts/network/dns/setup_dns.sh: /etc/resolv.conf edits and
ping -> runSystem; the WG_DEFAULT_DNS compose-file sed -> runFileOp.
Byte-identical in rooted; correct in rootless.

5c928fe9c0 feat(privilege): mode-aware privileged-op helper
Single place that decides how a privileged op runs by Docker mode:
- runFileOp / runFileWrite: /docker data-plane ops — rooted uses sudo (identical
  to today), rootless runs as the unprivileged install user (no root).
- runSystem: genuine system-admin ops, sudo in both modes, funnelled here so it
  can later be confined to a scoped sudoers allowlist.
Call sites converted to these are byte-for-byte unchanged under rooted, so
existing/live boxes can't regress; rootless gets the de-privileged path.
