Had you applied an update to the kernel with something like: rpm -U --root /var/lib/systemimages/images/XXX kernel-*.rpm At least once before when I did this, the rpm install mounted /proc on the chrooted /proc (i.e. /var/lib/systemimages/images/XXX/proc) and I ran into the same problem as you. It isn't a copy of /proc, it is the real /proc, mounted in two different locations. To unmount it, I needed to do a: chroot /var/lib/systemimages/images/XXX umount /proc although your reboot would have the same effect.
