Thanks for the pointer to checkservices.  Will read up on it.  That 
said, I think I'm still likely to stick with updating in rescue mode: 
For the specific server in question (my home server) some brief downtime 
isn't really an issue.  And at work, where nearly everything is cloud 
(and downtime would be an issue), we always just replace an instance 
with one running a newer version, rather than update-in-place.

Thanks,
