s, I think adding support for
'search' command is easy, but grub developers may not agree that this feature
is usefull.

This patch introduces support for plain encryption mode (plain dm-crypt) via
new module and command named 'plainmount'. The command allows to open devices
encrypted in plain mode (without LUKS) with following syntax:
plainmount -h hash -c cipher -o offset -s size -k key-size
-z sector-
plainmount (or manually type in console). Still, this helps in
some use cases (including some complex setup scenarios). Also, except opening
plain mode encrypted disks plainmount command can decrypt LUKS volumes if
master key is known.

not convinient for other grub code interested in this feature. I think the

GPG errors uniformly.
However, the way GPG errors are handled was not changed due to reasons
mentioned in previous discussion. Option -Z (sector size) was renamed to
-S. Also, unique cryptodisk UUIDs were added.

how device argument is sent (and
syntax used),
processing device blocks in 'configure_keyfile()' differes from processing a
file. I tested
grub_file_open() on a loopback device and it does not work. It makes sense,
because neither
'(hdx,gpty)NNN+' nor a loopback node on top of it is a fil

.
I am speaking about this:
loopback node (hd0,gpt2)2048+
plainmount node-c aes-xts-plain64 -h sha512 // works
plainmount (hd0,gpt2)2048+ -c aes-xts-plain64 -h sha512 // currently - no
Currently the second command does not work without loopback, I am thinking
about removing this limitation in plainmount.

It seems there is agreement to check that UUID size is longer than 1 and less
