stinky old bsd

if you're not running -current then, well, you've probably been rooted by now. me? i'm no target for balls-nasty uber hackers like gobbles and crew who have more time on their hands than i to research crap and make 0day sploits. hell even if someone with skillz wants to root my box what are they gonna get? my ~ has nothing more than a 40meg mail spool from the damn incidents list and maybe a personal message every few weeks for cheap viagra.

here's my script to update my system to openbsd-current. mostly borrowed from openbsd website and also here.

#!/bin/bash
#### fun ##
# Rebuild and install gcc
# Recompile a kernel
# Reboot and run make build

oh, and here's how to update a single spot in your openbsd source tree:
# cd /usr/src/usr.bin/ssh
# make obj
# make cleandir
# make depend
# make
# make install

or just in case you need to patch something:
# cd /usr/src/usr.bin/ssh
# patch -p0 < .../openbsd31_3.4.patch
# make obj
# make cleandir
# make depend
# make
# make install
