Well, here is one (you might not like it):
Make 2 (or more) entries in lilo.conf, each with a different
append: append=at_home, append=away.
After booting, notice that this comes up in /proc/cmdline.
Therefore, wherever /etc/network/interfaces would be called
from (not sure where), go:
if grep -q at_home /proc/cmdline; do
<use the interfaces for home>
if grep -q at_work /proc/cmdline; do
<use the iterfaces for work>
And don't do anything for "away".
I wouldn't say it's clean, but it would certainly work :)
(a slightly cleaner way would be to define an actual
parameter: append=interface=at_home. Then you parse that
from the script and use the corresponding file. That'd be
more flexible and less code.)
