Once fully booted into the rescue environment I do the following:

a) mount /dev/sda1 /mnt/sysimage/ (replace /dev/sda1 with your root partition or logvol)
b) mount -o bind /dev /mnt/sysimage/dev
c) mount -o bind /sys /mnt/sysimage/sys
d) mount -o bind /proc /mnt/sysimage/proc
e) chroot /mnt/sysimage

Regards,

Dan
