Yeah, the problem is when you have multiple network shares on the same
drive.   So, you have server:/mythtv/recordings exported and
server:/mythtv/archive exported and both exist on the same drive (or
volume or RAID or whatever).  Your mythtv backend mounts both and places
them into a storage group(s).  Since there's no common directory
available to network clients (only /mythtv is common, but it's not
exported), writing a file to the share won't help determine if they're
on the same disk.  The same issue could occur, but where only / were
common, so forcing the user to export the top-most common directory may
not make sense (you'll /never/ see me export my root :).  When we only
allowed one directory, it worked, but now...

32-bit or 64-bit?  (I'm assuming it's i686 or x86_64.)
