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

# LibrePortal docker-socket permission helper — the only root-privileged chmod of
|
|
# the docker sockets the manager may trigger (the type switcher hides/exposes the
|
|
# inactive/active mode's socket). Installed root:root 0755 to /usr/local/sbin by
|
|
# init.sh. Self-contained; the socket paths are computed here (never caller-
|
|
# supplied), so the scoped sudoers can allow it instead of blanket `sudo chmod`.
|
|
#
|
|
# Exit: 0 = socket found + chmod'd, 3 = socket absent (caller treats as not-found).
