And it was even faster on F17. I had F17 cold booting to a usable
Xfce desktop in 3.6 seconds by following Harald Hoyer's guide [1]:
Startup finished in 1470ms (kernel) + 2130ms (userspace) = 3601ms
But F18 and F19 now take 16 seconds on the same system:
Startup finished in 1.061s (kernel) + 15.299s (userspace) = 16.361s
The slowest component on F19 is this new "wait" service:
10.102s NetworkManager-wait-online.service
This service doesn't seem to do anything other than wait until the
network is fully up. This really skews unfavorably the boot time
reported by systemd-analyze. But if I mask that service and reboot,
everthing still appears to work fine and systemd-analyze reports a boot
time of only 6.2 seconds.
I wonder if there are other oddities like this that are skewing the
statistics reported by systemd-analyze.
