Actually, yeah. yum.log says: Dec 12 14:08:09 Updated: systemd-218-1.fc22.x86_64 and things started going downhill that evening. Damned if I know what 218 was doing to cause the issues. (Other RPM update that looked vaguely related was for selinux-policy, but again, damned if I know what a policy file could contain that would change the behavior...) Is it worth backing it to -217, or do we have a handle on the issue and systemd is just the messenger?
