A small hint from someone currently 2000km away from his machines:
I had to play with a new firewalling setup, meaning that there was a big
chance to lock myself out. Given that your machine will boot correctly,
but your network setup may be broken (no matter why), you could create a
script that brings the machine back to a working state. That is, install a
kernel that worked before, install old version of some scripts/configfiles
etc. and maybe even reboot it.
Then you make an estimate of how long you need to try your new setup, and
when you want to get back into your machine in case something goes wrong.
And finally, you tell at to fire up that script at a specified time, e.g.
# at -f rollback.sh + 10 minutes
See at(1) for details.
