Which is, if i'm not mistaken, how pfSense works. I tried it once but
there are things that m0n0wall just does better due to everything
running off a flash disk. For instance, when you want to turn off your
m0n0wall, you just pull the power because, unless you're writing a
config change at that point, there will be no disk activity. PfSense
is like any normal system, you've got to shut it down properly. Not to
mention for systems which go very long times between reboots (like
firewalls) the act of loading a large image once requires much less
disk activity than accessing each binary, config file and whatever
else every time you want to use them.

Or at least that's my thinking, could be wrong. The whole idea of
modularising fits much better into the pfSense design i'd say, where
as m0n0wall would, as you say, need a whole new image built to add or
remove features. Not saying that's a bad idea, I love the idea of a
menu driven build system where you select which modules you want and
it builds your image for you menuconfig style. Would mean tracking
down bugs might get a little more difficult though.
