- To properly run as a daemon an application should:
-
- - close all open file descriptors (see daemonize_closefds() for that)
- - (re)set proper signal handlers and signal mask
- - sanitise the environment
- - fork() / setsid() / fork() to detach from terminal, become process
- leader and run in the background (see daemonize_demon() for that)
- - reconnect stdin/stdout/stderr to /dev/null (see
- daemonize_redirect_stdio() for that)
- - set the umask to a reasonable value
- - chdir(/) to avoid locking any mounts
- - drop privileges as appropriate
- - chroot() if appropriate
- - create and lock a pidfile
- - exit the starting process if initialisation is complete (see
- daemonize_ready() for that)
