Subject: [PATCH] Try a different disk layout with LVM

This is based on a discussion here:
https://github.com/nix-community/disko/issues/889

Had to do it since the last one didn't even build and was based on a
cobbling of LLM (Claude) assistance, reading example files, and reading
the disko module definition file.
