@besser82lambday, what's the error you get?10:36
@lambdaybesser82: well, a bunch of services didn't start... fedora-import-state.service, systemd-logind.service10:37
@lambdayI tried booting into rescue mode with root, tried yum history undo last... didn't work due to no network10:37
@besser82lambday, ahh I see...  looks like some trouble with SELinux, I suppose...10:38
@besser82lambday, boot into rescue and `touch /.autorelabel`10:38
@lambdaybesser82: okay trying that10:38
@besser82lambday, then reboot as usual and see if it works then  ;)10:38
@besser82lambday, will restore all SELinux-contexts and will do an automated-reboot after on10:39
@lambdayokay I'm trying10:39
@lambdaybesser82: so .autorelebel shoud be in /root ?10:40
