James,

I am wondering if there needs to be new or additional blocker criteria 
since systemd is now default with F15.  My reasoning is:  with F14 and 
before, monitoring LVM snapshots was not a problem and shutdowns/reboots 
simply stopped the lvm2-monitor.  Now since there is a conflict 
introduced with systemd vs lvm2-monitor (bz 681582), the up-to-5 minute 
delay in shutdown/reboot could cause users to believe there is a problem 
that needs fixing and they may spend an inordinate amount of time trying 
to find the problem.  I looked at the release criteria and didn't see 
anything that would fit the new systemd scenario.

I know you indicated in the bz that it qualifies as an Nth for final, 
but it seems systemd vs the old services start/stop methods calls for 
some specific criteria.

What do you think?  Should I just go away and color in my coloring book 
or is there something here?  Reading the bz, looks like the fix is 
pretty much straighforward based on Lennart's comments.
