Well, in my experience, systemd has much worse documentation, is very inconsistent (or you could say it is constistantly brain-dead), and extremely unreliable and unpredictable, since it often hangs when shutting down and rebooting.

In my experience hangs usually happen from no time limits on units or excessively long time limits. I fried a NIC a while back and network-manager-wait-online has no time limit. Usually this isn't a problem, but the NIC was fried in a very unique way where it would continuously try to connect and then downgrade connections.

The bright side is this is all logged, trivially grep-able, and easy to fix.

systemd is like the registry. If you drink the koolaid and fully admit and adopt the decisions made, you’ll do ok, perhaps even good.

If you have 20+ years of experience, you’ll will NEVER get it to work the way you expect, might as well install Gentoo.
