autofs TODO list
----------------
* Support multimount entries.  (Quite messy: can't unmount the
  tree as a unit, probably needs locking while constructing the tree,
  and needs scaffolding if no entry for /.  Appears *very* difficult
  to do without threading!)
* /net support: need hostname resolver module (easy) as well as mountd
  query (easy) plus all the multimount entry stuff...
* Support URL format or -fstype= entries so we can automount nfs,
  smb, local filesystems... (eventually ftp, http...)?
* Additional lookup modules: [ng]dbm, db/hash, (hesiod?)...
* Document the intermodule interface.
* Document the program...
