FWIW, TIS/NAI Gauntlet _requires_ you to have gcc and stuff on it to work,
beacuse it rebuilds the kernel as part of the install process.
I'll second the idea of it being necessary to stop the intruder before s/he has
command prompt access on the bastion. Gone so far, the bastion is just a place
from which you launch attacks on other, more ripe, systems.
