| Most likely this is simply an ordering deadlock: systemd executes
| something that asks systemd to execute something else which however is
| order after the first unit. That is is not really fixable. At least I
| am have no idea what we could do about this.

We should at least print out/log what's happening when this happens.

Slightly related, it'd be really nice if we could have a way to poke
systemd to dump state.  I'm trying to track down a problem where boot
takes a while, and spawning extra shells and using serial consoles kinda
work, but it doesn't work that great.
