auto-biarch (x86_64 + i686) LiveDVD patch + ISO
by Jan Kratochvil
Hi,
finally created a LiveDVD ISO automatically booting x86_64 OS on x86_64
(and i686 otherwise). Regular users will not notice there exists any new arch
while they will benefit from the full performance of their PC:
http://people.redhat.com/jkratoch/x86bilive-2009062000.tar.gz (71KB)
It uses live_dir=LiveOS-x86_64 vs. live_dir=LiveOS-i686 to boot the image.
The syslinux patch provides "default-{x86_64,i386}" keywords in isolinux.cfg.
livecd-iso-to-disk is not patched/compatible with such image.
livecd-creator should create such ISO on a single run, not by merging the
output of two livecd-creator runs by a 3rd party app.
Regards,
Jan
Reasons:
* I still did not understand why I have to carry with me two media - both
x86_64 and i386 - when all the data perfectly fit on a single media.
* Why I have to try to boot x86_64 first to find out if the specific machine
is x86_64? Even common programmers do not know it, "Windows XP works here".
* The OS must "just work", it must be fun and easy. Requiring a special
technical decision before even starting the OS download is a showstopper.
* Checked that a regular user will on http://fedoraproject.org/get-fedora
still download terrible performance degradation of 32-bit OS although her
hadware is in 70%-95%(?) of cases x86_64. x86_64 is here for 6 years now.
* Arguing x86 may be faster than x86_64... I did not find any such case,
x86_64 is a more modern arch (more registers, PIC for free, better ABI).
We already hit the 2GB address space limitations. x86_64 is the future.
* All the friends of mine have 8Mbit+ ADSL and TB disks downloading many DVD
disks so some several more hundreds of MB are not something to notice.

Help with a problem I am seeing when trying to build a liveCD for FC13
by Jim Galarowicz
Hi,
I've been building a FC13 liveCD to showcase our OpenSpeedShop
performance tool.
The process was working well and I was creating liveCDs that I could
boot and exercise our tool. Then, I'm not sure what happened, as now I
see this when trying to build the liveCD:

Has anyone encountered this? It seems that the install_root isn't
getting the coreutils installed correctly or at all? I don't know if
something was killed in the middle of building and I'm stuck in some
intermediate setup state? I reinstalled the livecd-tools to see if
that would help, but it didn't.
Any help would be greatly appreciated.
Thanks,
Jim G.
THE DETAILS:
Steps I take to prepare the liveCD rpms:

1. Install Needed Development Packages
Note: Try to start with a base Fedora Core installation that includes
most development packages.
yum -y install libtool-ltdl-devel livecd-tools createrepo
2. Prepare The Local yum Repository
mkdir -p /var/www/html/yum/{base,updates}
cp /media/Fedora\ 13\ i386\

/var/www/html/yum/base/.
cp /media/Fedora\ 13\ i386\ DVD/Packages/*.rpm /var/www/html/yum/base/.
I had to copy these RPMs into /var/www/html/yum/base in order to create
the live os for OpenSpeedShop

3. Build Open MPI using provided spec file.
Copy created RPM to /var/www/html/yum/base/
4) Build toyprograms, webtutorials, and optionally the openmpi package using
the setup_and_build_rpms.sh script
Copy created RPMs to /var/www/html/yum/base/
5. Build OpenSpeedShop prerequisite packages.
Copy created RPMs to /var/www/html/yum/base/
6. Build OpenSpeedShop
Copy created RPM to /var/www/html/yum/base/
7. Create Local yum Repository
createrepo -dg
/var/www/html/yum/base/fce31f091be8211a394d8942fcf4f6cbeffa3d40d87b61af55a97b1a88b46987-Fedora-13-comps.xml

btrfs for Fedora 12 and 13 LiveCD/DVD ?
by Valent Turkovic
Hi,
how to make Fedora 12 and Fedora 13 LiveCD/DVD that is btrfs formated
and not ext4?
What options need to be enables in kicstart file so that
livecd-creator makes btrfs iso images?
I would like to also have compression enabled after btrfs image in
transfered to hard drive or SSD.
Has anybody tried this?
Thank you in advanced,
Valent.

[PATCH] Fixed buggy [[ "$DEV" =~ "/dev/loop*" ]] tests with new isdevloop() function
by Marc Herbert
This was accidentally working in old bash versions, not anymore in
Fedora 13's bash 4.1.7. Now using proper prefix matching instead of
the previous regex matching disguised as pattern matching.

mkbackup.py - Development of script to make LiveCD/DVD images from the running system
by Jasper Hartline
Here is what I have done so far on mkbackup.py
For anyone interested in knowing how this will be done..
I think I will use dump and restore to produce the Live images for now
which will be limited to Ext2/3/4
but I am glad to hear suggestions about supporting other filesystems
and or how to use any other tools.s
This should be interesting to see how it works as a backup media.
Being Live-runnable and installable later with much much easy using Anaconda.
The file is available at this URL and one attached. The on online will
be updated periodically.
Then I'll attach it to the mailing list here periodically too.

I'll keep banging away at it. I'm digging through the pyparted source.

List of previous issues with livecd-tools which should be addressed
by Jasper Hartline
In response to Jan Kratochvil's shell script I have attached a python
script which replicates
what she does in the bash shell script.
There is also a patch, which fixes up some regex/match in livecd-iso-to-disk
and another section which assumes our loop devices have extra numbered
partitions.
If you guys want to help beat mkbiarch.py Python script into shape maybe
we gan get it into the tools for livecd-tools.
The way you use it, is:
mkbiarch.py <x86 ISO image> <x64 ISO image> <Target Multi Arch Image name>

Comment added to https://bugzilla.redhat.com/show_bug.cgi?id=603277.
See https://bugzilla.redhat.com/show_bug.cgi?id=587411 livecd-iso-to-disk
--format fails with SD/MMC partitions.
The umount ${device}? will fail with an SD/MMC partition that uses a
device-partition# separator, such as the 'p' in /dev/mmcblk0p1
umount ${device}* would work, but would also unmount all partitions.
Having the partition number 1 hardcoded as USBDEV=${device}1 could also fail
with some SD/MMC drivers.
Attachment, https://bugzilla.redhat.com/attachment.cgi?id=413572&action=edit
, has
some replacement code:
- USBDEV=${device}1
+ partition=$( awk '$4 ~ /'${device#/dev/}'.*[0-9]$/ {print $4}'
/proc/partitions )
+ partnum=${partition##${device#/dev/}}
+ USBDEV=${device}${partnum}
