Split the single tree into three owner-isolated roots and fix the backup
permission failure (restic, running as the container user, could not write the
manager-owned /docker/backups).
Ownership helper (libreportal-ownership), rewritten for three baked roots:
SYSTEM_DIR (manager) CONTAINERS_DIR + BACKUPS_DIR (container user)
- reconcile now drives each tree to its single owner; backups + the WebUI dir go
to the container user (the actual fix). The container user reaches only the
WebUI bind-mount sources (configs/webui/*) via a scoped _webui_bind_access —
traverse the system root + configs, read configs/webui only, nothing else.
- defence-in-depth: refuse dangerous/relative roots even if mis-baked; new
backups-top action.
Baking: init.sh initRootHelpers now seds __SYSTEM_DIR__/__CONTAINERS_DIR__/
__BACKUPS_DIR__ (alongside __MANAGER__) into every helper at install — the trust
boundary stays root-controlled. svc/socket/appcfg helpers updated to derive from
the baked SYSTEM_DIR; the svc unit now exports LP_*_DIR so the processor resolves
roots authoritatively. A baking-safe '*"__"*' sentinel check survives the sed.
Install/uninstall: initFolders creates the three roots; initContainerLayer hands
containers + backups to the container user; uninstall removes all three
(idempotent on legacy single-tree installs). Remaining functional /docker
literals in init.sh (config reads, setupConfigsFromRepo, uninstall) parameterised.
Compose: the WebUI's two relative ../../configs mounts (the only cross-tree
relative mounts in the tree) are now absolute, filled at generation via a new
CONFIGS_DIR_TAG; CONTAINERS_DIR_TAG likewise for the LP_CONTAINERS_DIR env.
Live box unaffected: installed helpers + the live compose only change on reinstall/
rebuild (both of which fill the tags); the CLI-wrapper heredoc paths are baked in
phase 3.

Move the last runtime-critical root file-primitive subsystems behind
root-owned helpers so the type switcher + task service work under a scoped
sudoers:
- scripts/system/libreportal-socket: {rootless|rooted} {on|off} chmod of
the docker sockets (paths computed from config, not caller-supplied;
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
