I wonder if you can ever specify an export path that does not begin with 
a '/' -- is that possible when mounting an NFS server that exports, say, 
an old-fashioned HFS volume?

   "macintosh::Macintosh HD:Users:cel"

Looking for only the first colon gives the correct results in this case, 
but looking for ":/" would not.

Likewise on FAT32:

   "windows:\Documents and Settings\Chuck Lever\My Documents"
