We should probably have a proper written policy for the ip-up/down
setup.  I'll put something together from the ideas seen so far.  If
you've got a bright idea, or a weird PPP setup you think I should take
into account, please mail me.

This seems like a pretty good idea.  The only problem is how packages
are going to install their up/down scripts in a sensible manner.

Perhaps it would be better if we had sub directories that were based
on the connection type (the two main ones being internet and
non-internet) with the possibility of additional connection specific
directories.  Then most cases would be handled by mapping connections
to connection types.

It's definitely better to put as much of the intelligence as possible
in the main ip-up ip-down scripts, to avoid having to duplicate it in
all the run-parts scripts.

Is it worth combining the up/down scripts, so we pass a parameter
(``up'' or ``down'') and each script contains a case statement ?
