OK.

The encryption, AFAIK, shouldn't cause problems provided you can mount
the device.  If it's already mounted on /home, this isn't an issue.

This should work.  However, if /dev/mapper/thinkpad--t400-home is
already mounted on your /home, these are functionally equivalent.

The output shows that none of the setup scripts were run, which are
responsible for mounting things.

From this output:

Type                  plain

plain type chroots don't run setup scripts.  Use type=directory.
See schroot.conf(5) for more information; there's a "Plain and
directory chroots" section which explains this.
