The problem is still present in Xubuntu 22.04. It affects only the keyboard parameters.
It comes from the fact that certain parameters should ( from "man 7 casper" ) have aliases not recognized by the concerned program in file :
/usr/share/initramfs-tools/scripts/casper-bottom/19keyboard
Keywords that are not recognized are :
keyb, klayout, kvariant, kmodel
