icinga2 daemon reload
To check the configuration icinga2 daemon -C is used, but to reload you need to use either the systemd or init.d command.
Is it possible to create a different parameter, like -R to reload the daemon.
This would simply be to unify/simplify the typing, as icinga2 daemon -C and icinga2 daemon -R is much quicker and more intuitive, then icinga2 daemon -C and systemctl reload icinga2
Sounds like something that would benefit from #7349 rather than doing some more pidfile magic (alternative would be doing kill -HUP $(cat /run/icinga2/icinga2.pid) within that proposed command).
fwiw, systemd would already be handling the "pidfile magic" (on those systems, at least). e.g. nginx.service:
ExecReload=/bin/kill -s HUP $MAINPID
