Description Vít Ondruch 2018-07-08 12:41:36 UTC 
Description of problem:
With the update to systemd 239, I started to experience really slow boot. It appears the boot waits several times for some timeouts. First it waits before the GMD is shown, then it waits probably twice after login. That way, the boot takes like 3 minutes instead of 30 seconds I was used to.

Version-Release number of selected component (if applicable):
systemd-239-1.fc29.x86_64


How reproducible:
Always


Steps to Reproduce:
1. Reboot computer
2.
3.

Actual results:
The boot is slow, it seems it is waiting several times for some timeout.


Expected results:
Boot is smooth and quick.


Additional info:
For the time being, I have reverted to older systemd:

$ rpm -q systemd
systemd-238-8.git0e0aa59.fc29.x86_64

For example, see the first ~20s gap in the attached log between Jul 08 14:17:58 and Jul 08 14:18:20 or another between Jul 08 14:20:30 and Jul 08 14:20:54

It seems this helps:

And there is lot of AVCs, so this seems to be related to bug 1559281

Seems to be the same indeed, let's track this there.
