Maxim, I was merely rising to David's bait for some proof that people use
/bin/sh as an interactive shell. You're correct in saying that if /bin/sh on
my machines gets hosed it won't
matter too much - I'll use another shell to rebuild the machine, or boot
from an install CD
to get a shell. But as part of me fixing the machine, I'll put /bin/sh back

I didn't say anything about NSS and I don't intend to as I don't need it.
The debate should be held between people that need the functionality but
want it implemented in different ways.
As to performance loss, I really don't think I'm going to notice it - the
cheapest machine I can find in the UK is an Athlon 1800XP, that has a lot
more grunt than I need. This may not be true for others.
