[Rear-users] F8: can't find /dev/sda

I am trying to use rear with Fedora 8. I am running it with the
mkbackup option to an ISO file.
I am able to make a bootable DVD. However, when I try to run "rear
recover" after booting from the DVD I get the message, "ERROR: Required
physical device '/dev/sda' could not be found!" However, the block
device file, /dev/sda, is actually present.
When I searched for this error message, I found it in
is looking for /dev/sda in $TMP_DIR/physical_devices.
The physical_devices file is created by the function FindPhysicalDevices
from .../verify/GNU/Linux/10_describe_physical_devices.sh That function
looks for all the devices that have a queue directory in /sys/block/*.
Upon boot, there is no /sys/block/sda directory. However, if I manually
run start_udev, then the /sys/block/sda directory appears (along with my
Start_udev is present in /etc/rc.d/rc.sysinit, just like it is when I
boot from the hard drive.
If you're with me so far, here are my questions: Is udevd supposed to
run when booting from the DVD? If not, how is the /sys/block/sda
directory structure supposed to be created? If it is supposed to be
running, any thoughts on what would keep start_udev from starting udevd?
Thanks in advance for your help!
