Testing changes in current using a liveCD
Hello, I'd appreciate someone tell me if I'm doing something wrong. I want to test the latest ACPI changes in two Thinkpad I own (T410 and x201). I assume: 1. To test current I can just use the latest snapshot. 2. FuguIta LiveCD is regularly updated to the latest snapshot. In case I'm not wrong about some of those two assumptions. I tested my T410 and x201 with 5.7 release and June 17th 2015 snapshot without noticing any differences. I took in care the values showed by hw.sensors and apm, for example with both (release and snapshot) in x201 the values are arround: hw.sensors.fan0=3283 RPM hw.sensors.temp0=43.00 degC hw.sensors.itherm0.power0=5.00 W Please tell me if I'm wrong in any step.

We've also had users find recipes for mail servers on the 'net that only worked for obsolete versions of OpenBSD, and users who would rather follow the recipe on an obsolete version of OpenBSD than understand how it works and implement properly on supported versions of OpenBSD. There is a problem that many people on the 'net have -- they forget that any idiot can publish anything they wish on the 'net...the ability to render their thoughts into print or web does not mean it is accurate or of value...and google rankings There's also the issue of trust: here's this file I put out on the 'net, please download it, install it, and run it. enjoy! um...

That's a funny shaped hammer to drive something that doesn't look like a nail. * Some language vagueness which is somewhat confusing (4GB...what? RAM? Flash drive? space free?) * Significant lag between OpenBSD release and project updates. * Recreating something that is trivial for any experienced OpenBSD user to create on their own. It may be of use for new OpenBSD users...but are they really using OpenBSD? While a USB flash drive may seem a good starting point for new users, due to performance, I'd much rather suggest a junk PC one could dedicate to the (I actually started out thinking I was going to be singing the praise of Girish's creation of a Live OpenBSD CDROM as a true value add to OpenBSD...but was rather disappointed to find out it was just an installer for a USB Flash install.)

Olivebsd liveCD and using swap partitions

OliveBSD is several years out of date; it is based on OpenBSD 3.8. 4.2 is the current release, 4.3 will be released in 30 days. 2. I can't speak to OliveBSD, as I have never run it, nor looked at its documentation. You can manually add any OpenBSD addressable partition or any non-sparse file on an ffs filesystem as swap space via swapon(8) or swapctl(8). However, OliveBSD may or may not not be able to boot if you have insufficient RAM and no pre-configured swap space. You'll have to examine OliveBSD's documentation for guidance. 3. The only default swap space -- by default, I mean not configured by the administrator in /etc/fstab -- is the b partition of the boot drive, if the disklabel has a b partition with a filesystem type of SWAP. Everything else must be in /etc/fstab or manually configured. I'm not as famous as OliveBSD, but I offer a set of about a dozen different 4.2-based OpenBSD LiveCDs and LiveDVDs -- they do not have any swap space configured, and require a varying minimum amount of RAM to boot and run, anywhere from 96-288MB of RAM. If you were familiar with OpenBSD administration, you could boot one of my LiveCDs or LiveDVDS into single-user mode, configure swap space on a hard drive, then continue operation in multi-user mode, perhaps extending their usabililty below these minimums. OliveBSD may let you do something like that; or, it may not. www.jggimi.homeip.net is the top web page if you'd like to take a look.

Josh Grosse found it while building his live CDs, which can be found here, btw.: http://jggimi.homeip.net/livecd/faq.html The problem arouse with the KDE ones, the solution is to pack /usr/local into its own .iso (or perhaps a vnc mounted image would work as well) and mount it during startup.

Help with LiveCD/LIveDVD
Hello all,
Please CC to me directly as I am offlist...
I am building a LiveCD/LiveDVD based on OpenBSD 4.1 snapshot. I know this
is an unofficial page, but I followed the instructions here:
http://openbsd-wiki.org/index.php?title=LiveCD
I'm using 4.1 because of the libraries required on the LiveDVD. This
LiveDVD is used for in-house hardware diagnostics with customized programs
written for BSD. I thought it would be easier to boot from CD rather than
installing OpenBSD on every machine we need to use as a hardware testbed.
The only changes I made to the above instructions were to copy the
backup/{} directories instead of tar'ing them and unzipping them.
Everything works fine until the hang on boot with the message: Loading
CBDR.. The disc then fails to boot.
Relevant info:

Hello all,
Please CC to me directly as I am offlist...
I am building a LiveCD/LiveDVD based on OpenBSD 4.1 snapshot. I know this
is an unofficial page, but I followed the instructions here:
http://openbsd-wiki.org/index.php?title=LiveCD
I'm using 4.1 because of the libraries required on the LiveDVD. This
LiveDVD is used for in-house hardware diagnostics with customized programs
written for BSD. I thought it would be easier to boot from CD rather than
installing OpenBSD on every machine we need to use as a hardware testbed.
The only changes I made to the above instructions were to copy the
backup/{} directories instead of tar'ing them and unzipping them.
Everything works fine until the hang on boot with the message: Loading
CBDR.. The disc then fails to boot.

Re: Help with LiveCD/LIveDVD
Hi,
I hope you succeed. I'd be very itnerested in a live cd/dvd for obsd.
As you say, it's ideal to test hardware, but I don't have to time to
do it myself. Btw, why obsd 4.1?
Do you plan to upload the iso to some site? There were some projects,
like quetzal and olivebsd, but they died, I think.
good luck,
Pau

Well, the issue is that the kernel grows because of new drivers, but size of an emulated 2.88MB floppy doesn't grow. You either have to rip stuff out of the kernel or use the new method. I'd like to understand how the stuff in distrib works and playing with the instructions of Kevin Lo seems a good idea to me.

I haven't really understood what the 2.8MB device is for regarding the whole
process. Can anybody explain and propose a solution? Can't I just copy the
stuff to another device, that's bigger? If this is just for creating a floppy
image that's bootable and is insignificant regarding my live CD, can I just
delete these instructions from Makefile.inc?
The instructions by Kevin Lo say:
In the /usr/src/distrib/i386/ramdisk_cd directory, copy the two files bsd and
cdrom36.fs to the /livecd directory.
The cdrom36.fs in my case would be cdrom40.fs and has a fliesize bigger than
2.8MB anyway? I'm not able to spot any reference to any cdrom{version}.fs
file being created in the Makefile.inc. What's my problem?
Since I haven't been able to apply the patch
to /usr/src/distrib/i386/common/Makefile.inc with patch I deleted the lines
with a - in front of it in the patch file and added the lines with the +
at the appropriate lines. Just to avoid simple mistakes, I'll include the
whole Makefile.inc here. Sorry, if this is not appropriate.

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

Sam Fourman Jr. You might be able to fit everything on a normal 700MB CD, I need a 800MB CD for all my important apps, btw. this is all in the instructions. 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

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-miscm=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-miscm=115926553800205w=2
Regards,
ahb

#--- OpenBSD LiveCD ---#
- word # are 'links' to my private documentation, just ignore
# 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!)
# extract sets and manually adjust everything, normally done by install
# 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`
do
echo $log_file
done
# Now mount this partition with another OpenBSD system in order to create a
# (compressed) tar archive.
# NOTE: Do not forget the 'p' flag!
cd /mnt/ tar pczf ~/livecd_root.tar.gz *
# Of course you could also do this over the network, e.g.:
# cd / tar pczf - / | ssh [EMAIL PROTECTED] 'cat ~/livecd_root.tar.gz'
# We transfer this archive to our build machine and extract into our livecd
# directory we created earlier:
tar pxzf livecd_root.tar.gz -C /usr/livecd/
# We have to copy /var, /etc, /dev, /root and /home from /usr/livecd
# to /usr/livecd/backup:
# WARNING: Delete the shell history, viminfo and other documents we might
# NOT want to have on our CD:
cd /usr/livecd rm -i root/{.history,.viminfo}
cd /usr/livecd rm -i home/*/{.history,.viminfo}
cp -pR /usr/livecd/{var,etc,root,home} /usr/livecd/backups/
cp -pR /usr/livecd/dev/MAKEDEV /usr/livecd/backups/dev/
cd /usr/livecd ln -s tmp/xorg.conf.new xorg.conf.new # dirty trick, NEEDED!
# WARNING: Check for permission issues in livecd directory
# We have to create virtual partitions in memory (MFS) since we want them to be
# faster and more important writeable. On boot the content of the tar files
# located in /livecd/backups is extract into these MFS partitions.
# We have to modify the etc/rc script in order for this to work:

LiveCD thread
A few months ago, i put together some intsructions for making a livecd,
but didn't have the time to complete it, i'll post them here, and if
anybody wants,
we can work on it together and complete it and post it to the
mailinglist and perhaps openbsdsupport.org ?
So here we go :
# cd /usr
# export [EMAIL PROTECTED]:/cvs
# cvs -d$CVSROOT checkout -P src
# mkdir -p /livecd/backups/{var,etc,dev}
# cp -pR /var /livecd/backups/var
# cp -pR /etc /livecd/backups/etc
# cp -pR /dev/MAKEDEV /livecd/backups/dev

# rm -r /livecd/usr/src/*
