How did it check duplicates before that commit? The difference there
shows no checks being done on gluster at all... So semantically, not
sure it's a regression...  That commit just added a check to ensure the
host names and 'dir' weren't the same...  If anything it didn't go "far
enough" to check the source.name.

While rereading virStorageBackendGlusterOpen, I'm now wondering... Does
'dir' have to be provided?  The virStorageBackendGlusterOpen indicates
that 'dir' could be NULL and would default to "/"

ACK (although perhaps the STREQ_NULLABLE may need to be used for dir)
