IMO that's the price you pay for saying "install a whole bunch of random
stuff i haven't personally selected". if you cared, you'd take the time
to vet all selections yourself. if you don't care, accept whatever the
selection set gives you. if you discover later that you actually DO
care, then uninstall or disable the relevant package.

sounds like a bug in either the ipmasq package or in the selection set.  or

so it's solved.  where's the problem?

ok. i just don't think it's as big a deal as some people do. more to the
point, i think that doing the opposite (i.e. not enabling services by
default when a package is installed) will cause even more problems (and
confusion and hassle) to everyone else.

i.e. there's a tiny minority who are inconvenienced by daemons being
enabled when a package is installed. there would be a huge majority who
would be inconvenienced if the reverse were true. it looks to me like
it's an either/or situation (i.e. no way of satisfying both parties
at once - mutually exclusive needs) so it's a pretty easy choice to
make...cause the minimum harm/hassle/inconvenience.
