Okay, I can imagine there might be a case when you need to release all 
the replicated volumes referenced below a certain mount point. But these 
look like users' home volumes. I don't think you want to replicate 
those. Each of them probably has a mount point in "home", but then you 
just have to release the replicated volume "home" if/when there are any 
changes to it (and presumably it only contains mount points for the 
other volumes).  Unless I'm being really forgetful -- which can happen 
this time of the morning -- I don't see why you would ever replicate 
users' home volumes, thus you should never have to release them.

for i in `fs lsm /afs/@cell/home/* | \
           grep 'is a mount point for' | \
           cut -f8 -d' ' | \
           sed s/[\'#%]//g`; do vos release -id $i; done;

That's close. And ugly. And probably unnecessary for home volumes. I 
don't think you really want to do this.
