Are you sure the UUID is correct? It must be a LUKS UUID, as returned
by “cryptsetup luksUUID /dev/sdXXYY”, not an ext2 UUID.
Also, the ability to use LUKS UUIDs like this was not available in
0.10.0. So if you’re installing from the 0.10.0 USB image, you must
first ‘guix pull’.
Apart from that the config looks OK.
HTH!
