The argument to this option will be run at startup as a shell command (using `sh -c`) and can serve a similar function to `.xinitrc`: starting a service manager or other startup applications.  Unlike `.xinitrc`, the display server will not shut down when this process terminates.  Instead, as dwl is shutting down, it will send this process a SIGTERM and wait for it to terminate (if it hasn't already).  This makes it ideal not only for initialization but also for execing into a user-level service manager like s6 or `systemd --user`.
