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?
