Actually that was my very first motivation to even build an OpenBSD livecd. Wherever I encounter an 'interesting' machine (i386/amd64) I put the livecd in to see how good this machine would be supported. One thing I noted since my first livecd with 3.7: much more machines just work PERFECT (at least by dmesg output), even the weird P4s we have at school. The problem is that the boot sequence seems to scare some windows users: "What are all those messages, you didn't you wrack my PC, did you?" ;) Regards, ahb

You'll need something to save your kismet logs to before shutting down, of course. At runtime everything gets written to MFS partitions -> kismet works. Regards, ahb

Exuse me, but I don't see a point in posting a dmesg for a livecd, which by definition is portable. The dmesg depends on the machine I insert it into. If the question was: "Does it really work?" Yes, it does quite well, today I had the chance to test it with 10 different machines, all worked. Slowest was a pIII-500 with 128MB RAM, top showed 75MB mem usage after booting into X and with several apps started. One thing that bothers me is that I can only boot from the first CD drive, because cd0 is hardcoded in several places, but most of the time this doesn't matter. Regards, ahb

Re: new LiveCD instructions for OpenBSD
I have been looking for a OpenBSD Kismet Live DVD with a X Front end, I wonder if a person could actually have Kismet and x on a Live DVD? or would it have to be able to write to a Disk?

new LiveCD instructions for OpenBSD
Hello misc@,
Quite a few people sent me emails about my earier instructions, I posted
here some time ago:
http://marc.theaimsgroup.com/?l=openbsd-misc&m=1
Now I finally got around to update my instructions on how to create an
OpenBSD-based LiveCD/DVD.
They are far from perfect, but it works reasonably well (for me).
With the instructions you can either create a CD or DVD.
I'm too tired to test on amd64 at the moment, but it _should_ work
exactly the same (that is one of the reasons I love OpenBSD, no as much
pitfalls as in other OS).
Also thanks to Stuart Henderson for his recent post about the "new" CD
boot method:
http://marc.theaimsgroup.com/?l=openbsd-misc&m=115926553800205&w=2

# Since there isn't an official OpenBSD Live CD/DVD we will create one.
# We try to stick to the 'default system' as far as possible, this makes
# maintenance much easier.
# We need a current system and create a release with source code
# -> release
# Alternatively you could use OpenBSD stable/release with matching source code
# For the paranoid, like myself, using a more strict umask than 022 (e.g. 027):
umask 022 # XXX IMPORTANT for everything that follows!
# Create a directory, this will become root '/' on the CD.
# NOTE: If there is not enough free space on '/usr' you have to choose a
# different directory (of course you can do so anyway) and change the paths in
# all following commands accordingly.
# If you like copy/paste create a link from /usr/livecd to /path/foodir
mkdir -p /usr/livecd/backups/dev; chmod 755 /usr/livecd/backups/dev
# COMPLICATED way SKIP this! (Life is to short for this kind of stuff!)
#
# SIMPLE way to get this done
# Grab an empty hard drive and make a fresh nice and SLIM install of OpenBSD. As
# said above you need the source code to the version you install!
# HINT: Against all good practices ONLY create an 'a' partition since it will
# make creating the CD much easier than having multiple partitions.
# This includes all packages/ports you want to be on the CD.
# CD: X fine, but gets tight with (X) ports.
# CD 800MB: Most sets (including) X + a couple of (X) SLIM ports will fit.
# Sets: ALL -game
# DVD: Install whatever you want, there is lots of space.
# Sets: ALL
# You should configure the system EXACTLY like you want it to be on CD.
# WARNING:
# Some settings should be fairly generic, especially /etc/X11/xorg.conf should
# use the vesa driver and a resolution of "1024x768"!
# X -configure will be run to "autodetect" settings, if this fails, there is a
# fall back to generic xorg.conf, YOU put there.
# NOTE: Set a DIFFERENT root password!
# NOTE: You really want to start up X and login with your default user once
# before proceeding, because we want .fonts.cache-1 to be created.
# But shut X down again, before transferring files.
# Configuration hints:
# Remove:
rm -rf /usr/{src,ports}/* # CD only, for DVD you might even
extract them.
rm /etc/ssh/*key* # Some might want to keep them,
I don't
# We don't want other people to have a look at our log files
for log_file in `find /var/log -type f`
