hello
We are running cobbler-1.2.4-1 on RHEL5.2. Created initrd.img and
vmlinuz on another server(Fedora9) by livecd-iso-to-pxeboot command and
added the files as a distro to cobbler. All the steps are same as this
howto: https://fedorahosted.org/cobbler/wiki/HowToPxeAnyLiveCd
PXE can boot and download the big initrd.img but cannot find the rootfs.
Show me error like below:

---------------------
md: autorun ...
md: ... autorun DONE
VFS: Cannot open root device "Fedora-9-i686-Live.iso" or unknown-block(0,0)
Please append a correct "root=" boot option;here are the available
partitions:
0100 16384 ram0 (driver?)
0101 16384 ram1 (driver?)
0102 16384 ram2 (driver?)
...
...
...
010e 16384 ram14 (driver?)
010f 16384 ram15 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)

My pxelinux configuration file for the client created by cobbler:
/tftpboot/pxelinux.cfg/01-00-16-3e-aa-bb-cc

append initrd=/images/liveFedora9/Fedora9-i686-live-initrd.img
rootflags=loop root=/Fedora-9-i686-Live.iso syslog=10.0.0.135:25150
rootfstype=iso9660 kssendmac
ks=http://10.0.0.135/cblr/svc/op/ks/system/testvm

Any idea?
Thank you in advance
