Well - question related to this: does anyone use gamin with RHEL5/FC7 and 
homedirs on nfs? Does it work?
We are mounting homedirs from NetApp NAS250 and i saw some strange behavior 
with gamin under load - don't quite remember detail now, but i think it was 
huge wait times.
Didn't have time to troubleshoot - production server and all, but would love 
the come back to gamin at some point.
Oh - system is Cento5/ courier imap 4.1.3

Thanks
