Is rbash to be symlinked to /bin/sh? Is there anything else that might
need /bin/sh that would bark on rbash?
Either way, I don't know enough about it to know if it's worth the cost.
Seems to be script == program. If you don't trust it, dont' run it.
Luckily with a script you can easily see what it does and how.
I'll read up on it this weekend and give a real opinion once I know a
Of all tyrannies, a tyranny exercised for the good of its victims may be
the most oppressive. It may be better to live under robber barons than
under omnipotent moral busybodies. The robber baron's cruelty may
sometimes sleep, his cupidity may at some point be satiated; but those
who torment us for our own good will torment us without end, for they do
so with the approval of their consciences.
