Description of problem:
When boot in rescue mode, all seems mounted OK under /mnt/sysimage with exception bad mounted "/dev". Thus under /mnt/sysimage/dev aren't any device and work under chrooted /mnt/sysimage is problematic.

shm

Version-Release number of selected component (if applicable):
anaconda-11.5.0.51-1.fc11.i586 on boot.iso from 8-May-2009

How reproducible:
Tested on system on single SATA drive (/dev/sda) and on system with two SATA drives with 3 SW RAID1 partitions where rootfs is on /dev/md0.
Both systems have this problem.

Additional info:

in place of:
/dev/md0 on /mnt/sysimage/dev type ext3
perhaps would be better:
/dev on /mnt/sysimage/dev type tmpfs
