make upgrade overwrites /etc/mail/mailer.conf

[Matthew Dillon]

:But it doesn't the fix the problem of default config files which might
:be changed [or _are_ normally changed by the user]. Implementing
:merging seems even more a hack than this "overkill". A lot of admins
:use CVS or so to manage config files, which is even more overkill.

    The files in /etc/defaults are not supposed to be modified by anyone.
    You are only supposed to override them with files in /etc.  The whole
    idea of /etc/defaults is that the sysad does NOT modify those files,
    therefore we can overwrite them with a system upgrade.

    If we implement the same override mechanism for things like /etc/services,
    everything should work just fine.  We modify the files in /etc/defaults,
    and the sysad modifies the files in /etc.  No conflict.
