# OpenRC translation of net-misc/rustdesk/files/rustdesk.service.
#
# THIS FILE EXISTS TWICE, BYTE-IDENTICAL, at
# net-misc/rustdesk/files/rustdesk.initd and
# net-misc/rustdesk-bin/files/rustdesk.initd.  FILESDIR is per-package in
# Gentoo, so one copy cannot serve both packages -- they install the same
# daemon at the same path.  Edit both or neither; `cmp` between them is an
# assertion in the coverage harness, so a one-sided edit is caught.
#
# WHY supervise-daemon AND NOT command_background + pidfile.  The unit declares
# Type=simple together with PIDFile=/run/rustdesk.pid, which is contradictory
# and reads like a self-daemonising process.  It is not.  Measured on the 1.4.9
# payload: `rustdesk --service` stays in the foreground, spawns its own
# --server and --tray children, and never writes /run/rustdesk.pid.  systemd
# ignores PIDFile= under Type=simple, so the line is inert there too, and a
# pidfile-based OpenRC service would wait for a file that never appears.
#
# The daemon runs as root, exactly as the unit's User=root specifies.  Giving
# it a dedicated service account is a security change with a migration cost,
# and is deliberately not made here.
#
# WHAT THIS TRANSLATION LOSES.  KillMode=mixed signals the main process and
# then SIGKILLs whatever is left of its cgroup.  OpenRC has no cgroup-wide
# kill: `retry` below signals the supervised process only, so a wedged
# --server or --tray child can outlive a stop.  Check with `pgrep -f rustdesk`
# if a restart misbehaves.
