It _really_ depends on your mood. If you say you've run it for over a year on a production server, go for it :). What I tried to say, is that I wouldn't risk it on my production servers to run 2.1whatever. I can't make that decision for you, since you're the sysadmin. You're right that 2.1 has been pretty stable for the last half year, but it also had its rougher times (as in ooops'ing on vserver startup). That's one thing I can't risk.

You could easily eliminate the grep by using -links 1 in the find command.
to delete those listed files, add to the end:

Would be far more efficient to use -print0 | xargs -0 rm -f.
Did you hear anything on this? I ran the query on a 12+ guest system (
all FC5 ) and it ran for well over a couple of minutes before I got
tired of watching the output. This leads me to think I've got lots of
orphans. I'd like to get rid of them ( Save the inodes! ) but want to
understand what I'm doing first. Rather not fubar a live system.
This should be a perfectly safe command, I always run some cleanup after
hashifying my guests.
I'm not sure I fully understand how vhashify works. Where are the
actual files located. Are the entries in
/etc/vservers/.defaults/vdirbase/.hash/
links to the actual files and then each guest links to these -- links?
Those would be the actual files (the file in the .hash directory is
created by vhashify as a copy of the file it's hashifying), and vhashify
then creates links to those in the guest(s).
