      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:

      	done

      		local procfile=${ossfile##${alsastatedir}/oss}

      		if [ -e /proc/asound/"${procfile}"/oss ] ; then
      		    cat "${ossfile}" > /proc/asound/"${procfile}"/oss 
      		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.
