[ale] [systemd] Boot speed

[leam hall]

Possibly separating this discussion out into component parts. We'll
see how it goes.

I don't see boot speed as a game changer for systemd, even if it is a
lot faster. If you're booting your desktop then you're probably
already used to "push the power button, hit the head, grab some
coffee" routine. If you system isn't up by then maybe there's an
issue.

For servers, if you really want uptime, why aren't you redundant?
Reboot time is again not an issue if the service stays up.
