The proposal to merge ~dbungert/curtin:cryptoswap-dmc-type into curtin:master has been updated.

Commit message changed to:

dm_crypt: create and use cryptoswap as PLAIN

Previously, cryptoswap was acting strangely, in that at install time it
was considered to be a LUKS2 device and durign actual system use it
would be considered a PLAIN device, in the cryptsetup(8) meanings of
these terms.

This caused problems when attempting to reference the device, as we
would do get_volume_spec(), the returned /dev/disk/by-id/dm-uuid-...
value would be wrong - it would change from dm-uuid-CRYPT-LUKS2-... to
dm-uuid-CRYPT-PLAIN-...

As the real runtime behavior is to be a PLAIN device for cryptoswap,
stop creating it as a LUKS2 device and just use it as a PLAIN device,
which doesn't involve a "create" step at all, you just open it as PLAIN
directly.
