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.

How I do to use livecd-creator in CentOS 3 (kernel 2.4) ?
by Thiago Braga Santana
Hello.
I relly need build a CentOS 3 (or similar with kernel version 2.4) livecd.
I already have installed the "livecd-tools". But I get problems in moment of
mount the ext3 image, because "/sys" does exist.
Somebody can help me?
Exist any version of livecd-creator for kernel 2.4?
Regards

You should get a desktop icon, but if you don't and just need to install,
you can run liveinst from a shell.
liveinst comes from anaconda, so it pretty much has to be there.

Install to hard-disk option missing in custom livecd
by kala
Dear friends
I had made a custom live cd with fedora 9 with packages from a
fedora-9-dvd.iso and it worked like a charm with option which installs to
hard disk and now i have tried similar with F11 with packages from
fedora-11-dvd.iso , it also worked but the " install to hard disk " option
is missing , I am sure that i have missed a particular package, can you
please tell me the list of packages ( main + deps) which allows me to enable
this option
with regards

Re: [Fedora-livecd-list] rebootless liveos installer - rliveinst v0.3 for f11
by Jane Dogalt
Also, this does not yet work with a --home style liveusb, and overlays might not work either. And it doesn't play well with the automatic swap enabling, so before running the script, do 'swapoff -a'. And what the heck, for good measure you may want to do a 'umount /mnt/live' for good measure beforehand as well.
But other than all those caveats- it did just actually do its job on a real hardware test (acer aspire one).
Obviously much work remains to be done, but it's rapidly approaching where I've always wanted to see it.

[PATCH] don't need to checkMBR() for loop devices
by Martin Dengler
livecd-iso-to-disk.sh doesn't do the right thing w.r.t. loop devices
and MBR detection. I don't think this is intentional, but it
currently requires loop devices to start with an MBR, by virtue of
getdisk() being a NOOP for loop devices and checkMBR assuming that the
disk must need an MBR. checkMBR() should just ignore loop devices
like other key functions do.

Re: [Fedora-livecd-list] auto-biarch (x86_64 + i686) LiveDVD patch + ISO
by Jane Dogalt
Very cool. Now if only you can go tri-arch with ppc. Actually I'm just kidding, I don't care about that unless I can get fixstars to hire me, or someone to give me a ps3.
Out of curiosity- has anybody yet mastered a good spin that also plays video when inserted into a typical dvd player? I don't think there are any issues with that, but wonder why I haven't seen that before. It seems like packing in a kickass intro-to-fedora video that people could play on their DVD player, would be a great feature, that might help a certain class of new users feel more comfortable with the process. I.e. it feels pretty safe to watch a DVD, versus running some strange software on your computer.
Thanks again Jan, very cool feature.
