Description Othman Madjoudj 2011-06-20 03:08:34 UTC 
Description of problem:
I've tried to create a RHEL6 based live CD on Fedora 15 with livecd-creator, everything work correctly except when I try to run the composed ISO its fails with 'Can't mount root filesystem'

Command used:
livecd-creator --config=rhel6beta-livecd-min.ks --cache=/var/cache/livcd

Version-Release number of selected component (if applicable):
livecd-tools-15.7-1.fc15.i686
python-imgcreate-15.7-1.fc15.i686


How reproducible:
100%

  
Actual results:
RHEL6-based live can't boot

Expected results:
RHEL6-based live should boot

Additional info:
I attached the kickstart and kernel boot output (I used qemu-kvm)

Comment 3 Brian Lane 2011-06-20 16:07:19 UTC 
The kernels for F15 and RHEL6 support different compression methods. When livecd-creator is running on a F15 system it will expect that the target is F15 or later. Try passing --compression-type=gzip to livecd-creator and see if that works for you.

--compression-type=gzip option makes a bootable ISO, thanks.
