Can LFS be copied from 1 hard drive to another after the build?

D'oh!  "rsync -ax" won't recurse into mount points so that's safer.
/dev is OK if it's a regular file system, "rsync -a" handles device
nodes fine.  If you're using devfs/udev it's probably a different
story.

For real peace of mind, boot off a Knoppix Live CD or similar, mount
both the old and new partitions to temporary directories and rsync
them.  Now you *know* exactly what you're copying.  Works for /
partitions too!
