Hammer PFS weirdness when encrypting root

:I ran into a weird issue while building an encrypted root filesystem. I
:used the script below to build the encrypted root. Right after this runs,
:"ls /mnt/usr" and "ls /mnt/var" show the expected files and directories.
: However, if I unmount root and remount it, I find that the contents of /usr
:and /var have swapped. I can easily fix it by renaming /pfs/usr to /pfs/var
:and vice versa. The script works fine on a non-encrypted root, so I'm
:wondering if it is somehow related to the mapper. I'm running 188.8.131.52.
The issue is that you are cpdup'ing your current root onto the new
:cpdup -o / /mnt
And that is overwriting the PFS softlinks you created in /mnt/pfs.
I've made similar mistakes myself every so often.
