Ran 'cat /proc/mounts', found that dev/pts was mounted under /mnt/lfs, successfully unmounted it, tried to unmount /mnt/lfs again without success.

Only user logged in is the root I logged in with to remove the /mnt/lfs partition... I'm not chroot'ed either... :-/

Have you unmounted /mnt/lfs/proc' ($LFS/proc)?  Also have you mounted
anything else there.  (Try cat /proc/mounts to see what it thinks is

Other that that, exit chroot; make sure that no user is within that area
and it should unmount
