Cool. :)

Assume netbase for the moment.

(eth0 == $interface, one assumes)

Yellowpages does. So does other stuff. Check /etc/rpc if you're *really*
curious. Add an "exit 0" at the top of /etc/init.d/portmap if you don't
need it, personally.

For PCMCIA netcards, you need some way of saying all this stuff,
and also that you don't want to do this automatically at bootup, but
that pcmcia-cs or something will take care of it when a card actually
gets inserted. Possibly a "noauto" option, as per fstab, or something
similar. That way pcmcia can just "mount" it later.
For DHCP, BOOTP and IPv6 (well, DHCPv6) clients, you need some way of
saying "this other package will take care of working out how to deal
with addresses and routing and whatever else, so just run /sbin/foo".
Not requiring a netmask would probably be nice, and having an optional
broadcast address might also be nice.
Note that
eth0:1 194.77.132.134 netmask 255.255.255.224
would be a perfectly reasonable line to have above, btw.

Adding "metric 1 external" would probably be a good move. (metric 1 means
it's one hop away, external that routed should completely ignore this
route) "man routed" for some info on how /etc/gateways is meant to work.
(Bug#23703, fwiw. *sigh*)
I guess just adding "if there's an interface for this network/host" around
the code to "add this gateway to the routing table" would make this work
for noauto and stuff above too.
Note also that it's just plain not possible to list all routes here,
for clients that use DHCP and friends in particular (where the routes
aren't known in advance and can even change).
I am, btw, currently thinking that the IP aliases / virtual hosting stuff
being discussed in another part of this thread should go in a completely
different package to netbase. netaliases or netvirtual or something,
perhaps. It seems to me that this gets rid of a large part of the "perl,
sed, awk, oh my" problem for boot-floppies.
Cheers,
