For example:
a) start daemon1 b) if daemon1 returns no startup errors, launch daemon2 c) if daemon1 returns any startup error, doesn't start daemon2 and exit.
Is it possible to do this with systemctl??
In this specific example I'd probably do it as two service units with daemon2 wanted by multi-user.target and requiring the daemon1 service...
That was daemon2 will want to be started by default and dependencies mean that will start daemon1 in the process of doing so... But since 2 requires 1 if 1 fails to start for some reason then 2 won't be stated.
Thanks james. That was my first idea ... But some of these daemons can conflict with some system packages. For example I need to startup two rsyslog daemons, and this can be a problem ... or not??
