[etch-users] Etch 3.20.1 released

[Jason H. <jh...@ap...>]

A small patch release to address a few minor things:

* The warning that etch is defaulting to UID/GID 0 because a user or group was not found is now shown only in debug mode.  Change contributed by Marjorie Saltman.
* Fixed a typo in the client Rakefile
