Hello list,
This is my first post here, and if this mail is not correct for this list,
please redirect it where appropriate.
So here goes my problem and a fix....
I've been using /usr/bin/livecd-creator and /usr/bin/livecd-iso-to-pxeboot
to setup my PXE booting environment on Fedora10, with success.
Recently I moved to Fedora12, and PXE booting fails with following error:
dracut: root was live:/LiveCD.iso. liveroot is now /LiveCD.iso
dracut: FATAL: Don't know how to handle 'root=live:/LiveCD.iso'
dracut: Refusing to continue
I've looked into the issue and found that "root=live:/LiveCD.iso" setting
is not correctly handled in /cmdline/30parse-dmsquash-live.sh for the
initrd0.img, or the /boot/initramfs-2.6.31.6-162.fc12.i686.img file.
Also udev handling changes in /init script does not seem to handle the
ISO image settings.
So, I hacked up a patch to fix the issue.
The patch adds new "liveiso:" directive for the root image, and adds
udev rule file accordingly.
Please review and let the fix get into the Fedora repo?
Thanks in advance,
Haro
