    Sure, that seems pretty reasonable. Here’s the init script for sddm:

    #!/usr/bin/openrc-run
    
    supervisor=supervise-daemon
    command="/usr/bin/sddm"
    
    depend() {
        need localmount
    
        after bootmisc consolefont modules netmount
        after ypbind autofs openvpn gpm lircmd
        after quota keymaps
        before alsasound
        want logind
        use xfs
    
        provide xdm display-manager
    }
    

    That’s it. That’s the whole thing.

    That’s a pretty simple one though, so here’s Alsa. It’s a more complex one:

    		fi
    	done
    
    	eend 0
    }
    
    save() {
    	ebegin "Storing ALSA Mixer Levels"
    
    	checkpath -q -d -m 0700 -o root:root ${alsahomedir} || return 1
    
    	mkdir -p "${alsastatedir}"
    	if ! alsactl -E HOME="${alsahomedir}" -f "${alsastatedir}/asound.state" store; then
    		eerror "Error saving levels."
    		eend 1
    		return 1
    	fi
    
    	for ossfile in /proc/asound/card*/pcm*/oss; do
    		[ -e "${ossfile}" ] || continue
    		local device=${ossfile##/proc/asound/} ; device=${device%%/oss}
    		device="$(echo "${device}" | sed -e 's,/,_,g')"
    		mkdir -p "${alsastatedir}/oss/"
    		cp "${ossfile}" "${alsastatedir}/oss/${device}"
    	done
    
    	eend 0
    }
    
    start() {
    	if [ "${RESTORE_ON_START}" = "yes" ]; then
    		restore
    	fi
    
    	return 0
    }
    
    stop() {
    	if [ "${SAVE_ON_STOP}" = "yes" ]; then
    		save
    	fi
    	return 0
    }
    

    That’s definitely longer than a systemd service, but you’d have to write an awful lot of them to be more code than all of systemd. Overall the entire /etc/init.d folder on my PC where all the init scripts even for the stuff I’m not using are stored is a grand total of 147.7 KiB. Not exactly an unmanageable amount of code, in my humble opinion.

      Its certainly easier to read than most old init scripts and I can see why some distros and openbsd would pick it over systemd for more control. I’m not likely to pick a distro that uses it anytime soon, but i can see why some do.

        That’s totally fair. I’m not some weird evangelist or anything. I just like options and think OpenRC is kinda neat. There’s nothing wrong with systemd, and honestly it’s more work using other options. Not for the actual init system, but for some of the other stuff systemd does. I’ve had to learn cron, and that has been… interesting. It feels like all of the documentation around cron just assumes you already know how cron works. I’m still not sure if I’m doing it right, but I’ve had a good time and my computer works, and really that’s good enough for me.
