Nah, who needs that stuff anyway :-) Note that even my desktop and
laptop work fine without initrd, systemd and CONFIG_CGROUP nonsense. And
while they are bloated with useless crap like *Kit and others, simply
because I can't get myself to rebuild enough to get rid of the
dependencies, I utterly hate them being around.

Except that it waits a random amount of time, long enough for me to
think the machine didn't come back up and power cycle again. The random
delay is _waay_ longer than a regular reboot cycle and totally destroys
the usability.

So you don't recommend people use server type setups? Quality
engineering that!
