I was thinking about this the other day in fact and i had a couple of
questions. First off i agree that the daemon should be restarted or at
least be offered (see discussion below) to be restarted during the
installation of an updated package.

I was wondering how the rpm process is exposed to agents that use it
(e.g. yum, apt). Do yum and apt simply parse standard output from rpm or
is there some sort of sane notification method they are using to drive
an event (via rpmlibs or somesuch)?

Along this same issue packages like mplayer plugin "require" mozilla's
rpm to be installed when in fact firefox works just fine as well. Is
there any normal way for the packager to specify that either firefox or
mozilla should be installed (but not necessarily both). I recognize that
this could cause some issues with dep resolution (e.g. prompting on
which to include in dep inclusion if neither is installed) which is why
i asked the earlier question that refers to how yum and apt communicate
with rpm (or possibly rpmlibs?).

If these are total non-issues forgive me and ignore the post but i have
run into CLI output a number of times while running various GUI's
provided with fedora (rhgb, gyum, synaptic). This makes them seem like
simple wrappers simple interpreters (that fail on abnormal behavior or
output) to the CLI versions instead of integrated alternative views
based on event driven architectures.
