Upstart provides a PID 1 that is absolutely rock solid. It's true that it's
more complex than sysvinit, because it's more featureful;
The same is valid for the comparision of upstart vs systemd.
And of all the concerns raised when Ubuntu (and Fedora and OpenSuSE)
switched to upstart, "PID 1 is buggy and crashes" was not one of them.
With only Ubuntu being the remaining distribution sticking to upstart, while nearly everyone else has switched to systemd.
This is not theoretical. upstart has been PID 1 in Ubuntu since 2006. It
*is* absolutely dependable and reliable.
Upstart has had its problems, too [1]. And, honestly, the way this bug was handled left me with little confidence in upstart.
