Bug 458470

Description of problem:

livecd-iso-to-pxeboot when run against the F9 x86_64 live ISO as described here:  https://fedorahosted.org/cobbler/wiki/HowToPxeAnyLiveCd results in the PXE CD booting but not entering inside of the "f9live.iso" "stage".  Basically if one does an ls at the bash prompt the pxe booted image gives you can see the ISO (f9live.iso) but you have not entered inside of it.  This seems to indicate something may be wrong with the init script as the root flags and such appear to be correct as I'm using the flags basically as the livecd-iso-to-pxeboot script generates them.

Version-Release number of selected component (if applicable):

I'm using the livecd downloaded from the Fedora torrent for x86_64, though here's what I was using for livecd-iso-to-pxeboot:

[mdehaan@localhost cobbler]$ rpm -q mkinitrd
mkinitrd-6.0.52-2.fc9.i386

[mdehaan@localhost cobbler]$ rpm -q livecd-tools
livecd-tools-017.1-1.fc9.i386

Yeah, that's the key point, which you put much more eloquently than I did.  This
is all based off of memory from many months ago, though, so I could be totally
off my rocker.  I think you'll have to look at the init script to tell for
certain; please share if you find out, since I'm curious to know (again?).

Further discussion on #ovirt pointed to this code being part of mkinitrd now:

Meanwhile on #ovirt apevec says the ovirt CD does not have this problem.  So perhaps there is something specific about livecd-tools doing this -- either size related or path related.  I'm not sure how to chase it, but plan to do some more testing Monday with other live images including ones I've built myself.
