I upgraded mailman from 2.1.5 to 2.1.7. In doing so, portage overwrote my custom config file at "/usr/local/mailman/Mailman/Defaults.py". It would be nice to have the directory "/usr/local/mailman/Mailman" treated the same way as "/etc" when dealing with updated config files (ie, naming new config files "._cfg*" instead of automatically overwriting them). I do not know the inner workings of "etc-update", but that script may also need updating if you decide to protect "/usr/local/mailman/Mailman".

The file in question starts with following warning. # NEVER make site configuration changes to this file. ALWAYS make them in # mm_cfg.py instead, in the designated area. See the comments in that file # for details.
