make upgrade overwrites /etc/mail/mailer.conf

[Matthew Dillon]

:Another solution could be using default files (/etc/defaults/services) 
:and add overrides/custom entries in /etc/services.

:Too bad that I have no idea how we could do this, since -alot- of tcp/ip 
:tools use /etc/services directly. Any way to wrap this?

    No tools should be using /etc/services directly.  They should all be
    using e.g. getservbyname() and friends.

    Pesonally speaking I really like the idea of having /etc/services
    and /etc/defaults/services.
