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 task-processor systemd helper — the only root-privileged management
|
|
# of the libreportal.service unit the manager may trigger. Installed root:root
|
|
# 0755 to /usr/local/sbin by init.sh. Self-contained: it GENERATES the unit from
|
|
# config (mode + install-user uid + the baked manager name + fixed script paths)
|
|
# — it does NOT accept unit content from the caller (that would be root: an
|
|
# arbitrary systemd unit runs anything as root). So the scoped sudoers can allow
|
|
# it instead of blanket `sudo tee /etc/systemd/...` + `sudo systemctl`.
|
|
#
|
|
# Idempotent: only rewrites + daemon-reloads + restarts when the unit changed,
|
|
# else just ensures it's enabled + running (no needless restart of in-flight work).
