The bug you just tried to hijack is related to the Anaconda installer,
and kickstart files used for it. Not livecd-tools or livecd-creator.
livecd-creator is tied heavily to Ext3 currently, and unless you are
willing to write patches currently
there is no quick fix to use BTRFS on the LiveCD, LiveCD is SquashFS
anyways, the only part which is
added which has a usable filesystem is the COW Ext3 in an overlay file
which is created when using livecd-iso-to-disk
Anaconda and livecd-creator or two different things.
Hmm, then I don't understand how guys in the mentioned bugzilla
entry
got it working? Are they even talking about livecd btrfs in this bug -
https://bugzilla.redhat.com/show_bug.cgi?id=571910 ?
If there is a quick fix for this, please tell me what I can do and how
to edit imgcreate/fs.py so that btrfs livecd image creation works. I'm
really eaget to try btrfs via livecd image.
