Boot problem (jreiser)

[2011-08-06 0000 UTC] Upon boot of DVD, then dracut drops to shell with the message:

 Warning: No root device "live:/dev/disk/by-label/Fedora" found.

The file is present as

 /dev/disk/by-label/Fedora 16 x86_64 DVD

with those three spaces. Reboot with quoting (single, or double, or backslash) also fails. Altering the boot parameter to


also fails [that name is in my /dev/disk/by-id].

[2011-08-06 1700 UTC] After modifying pungi so that the label of the DVD has dashes "Fedora-16-x86_64-DVD" and changing the boot command line to include the dashes "root=live:CDLABEL=Fedora-16-x86_64-DVD", then dracut still complains "No root device \"live:/dev/disk/by-label/Fedora-16-x86_64-DVD\" found". The device is there, symlinked to ../../sr0 ==> /dev/sr0, and that is the correct name of the hardware drive.

[2011-08-07 0400 UTC] In the emergency shell after dracut cannot find the root, I can find it by:

 mkdir /mnt1 /mnt2 /mnt3
 mount -o ro,loop /dev/sr0 /mnt1
 mount -o ro,loop /mnt1/images/install.img /mnt2
 mount -o ro,loop /mnt2/LiveOS/rootfs.img /mnt3

but I cannot find how to specify that in a "root=live..." that dracut understands. It's also a mystery why so many mounts are necessary.
