> 10 seconds for a service seems obscene. 1 minute is so bad it's hilarious, but also really annoying. I feel like filing a bug against anything that takes more than 1/2 second but maybe that's being overly generous (by filing the bug, that is).

It's a 3+ minute userspace hit on the startup time where the kernel takes 1.9 seconds. Off hand this doesn't seem reasonable, especially sendmail. If the time can't be brought down by a lot, can it ship disabled by default?

Can you provide from console hostnamectl ?
