With `pid:!/path` Finit does not manage the file -- the daemon creates it on start and removes it on graceful exit. If the daemon dies before cleanup (SIGKILL, OOM, segfault, exit during startup) the file lingers and can block the next instance from starting, e.g. dbus-daemon refuses with EEXIST and the restart loop fails. Remove the file when it still names the just-reaped PID and that PID is no longer alive (the liveness check guards against reuse). Called from service_cleanup(), and from service_monitor()'s forking+starting branch where cleanup was previously skipped. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Finit is a fast, simple alternative to SysV init and systemd, designed for small and embedded Linux systems. It can also run on desktop and server systems, like finix.

- 🛠️ Buildroot embedded Linux,
- 📦 Debian GNU/Linux,
- ⛰️ Alpine Linux, and
- 🌌 Void Linux
Note
Finit can run on various Linux distributions, but the bundled install scripts are examples only. They have been tested on amd64 (x86_64) systems with standard configurations.
For embedded systems, see these Buildroot-based examples: myLinux, Infix, or br2-finit-demo.
