This quick patch will "fix" the problem when using "mount -a" or any
kind of netfs service which calls the mount.glusterfs script. IIRC this
maining list filters out attachments, so here it is (EOLs are munged
up, fix accordingly) :

This is probably not portable at all (tested only on Fedora/RHEL), and
I'm sure there must be a much more elegant way to fix the problem ;-)
