I was thinking 'on the fly', but it's a good question... how does
one 'comment out' a service in /etc/services that exists in
/etc/defaults/services. Detecting '#...' in /etc/services and
making that also remove the line from /etc/defaults/services would lead
to mass confusion.
I don't think it's necessary that we support service removal
immediately, but if we were to do it I would suggest something like
'-<servicename> ...' in /etc/services to remove a service entirely.
Still not perfect, but workable if the number of services being removed
is fairly small. A major ripout would pretty much require overwriting
the file in /etc/defaults and I don't think it would make sense to
try to hack up the build system to support that kind of thing.
