autofs v3 TODO list
-------------------
* Additional lookup modules: [ng]dbm, db/hash...?

autofs v4 TODO list
-------------------
* Completely rewritten kernel protocol, use multithreading rather than
  processes in the daemon.
* 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...
