Optimization when starting services when their dependencies fails to start

[stacyharper]

As you can see in the next example, service1 get restarted 4 times:

$ cat /etc/init.d/service1
#!/sbin/openrc-run

start() {
	echo "SERVICE 1 FAILED"
	exit 1
}
$ cat /etc/init.d/service2
#!/sbin/openrc-run

start() {
	echo "SERVICE 2 FAILED"
	exit 1
}
$ cat /etc/init.d/service3
#!/sbin/openrc-run

start() {
	echo "SERVICE 3 FAILED"
	exit 1
}
$ cat /etc/init.d/service4
#!/sbin/openrc-run

start() {
	echo "SERVICE 4 FAILED"
	exit 1
}
$ cat /etc/conf.d/service2
rc_need="service1"
$ cat /etc/conf.d/service3
rc_need="service2"
$ cat /etc/conf.d/service4
rc_need="service3"

$ doas rc-service service4 start
SERVICE 1 FAILED
 * ERROR: service1 failed to start
SERVICE 1 FAILED
 * ERROR: service1 failed to start
 * ERROR: cannot start service2 as service1 would not start
SERVICE 1 FAILED
 * ERROR: service1 failed to start
SERVICE 1 FAILED
 * ERROR: service1 failed to start
 * ERROR: cannot start service2 as service1 would not start
 * ERROR: cannot start service3 as service1 would not start
 * ERROR: cannot start service4 as service1 would not start

I would expect for OpenRc to try to start it once, and fail immediately, and for the stderr message to look like:

$ doas rc-service service4 start
SERVICE 1 FAILED
 * ERROR: service1 failed to start
 * ERROR: cannot start service2 as service1 would not start
 * ERROR: cannot start service3 as service2 can not start
 * ERROR: cannot start service4 as service3 can not start
