Oh, oops, I did indeed forget :)
I still haven't tried cgd under NetBSD, and for exports I have -alldirs
anyway (just easier) and export every partition except /var which makes
no sense to export. I don't need much security against myself :) I'm the
only nix-like user in the *area*, saying nothing of the local subnet
which is the only one allowed, so it really isn't a problem.
But I'll keep that in mind for when I do set up truly shared servers.
I find security the most fun part of any system setup, and this is where
the BSDs really shine. Just the feeling of research and refinement into
our security tactics leading to a final "here's my IP, good luck :)"
posted to a bunch of script kiddies and laughing as their Linux-oriented
attempts fail. Okay, I've never done quite that, but still knowing that
nobody's going to get lucky is good. You don't get this satisfaction
with performance tuning, the 'other' part people sometimes spend a lot
of time and effort on. "Yay - I boot 1 second faster and get a 3% higher
bonnie block read score! And it only took three years and five
reinstalls per week!" = stupid.
