I know you meant well, but, don't talk to me as if I'm the village
idiot.

I said I don't run snaps or Ubuntu, which is nothing to do with lack of
understanding (*)

I'll contact a couple of people in Canonical to obtain what I need.

(*) I worked as a kernel maintainer for Canonical (Ubuntu) from 2007/8
and I worked as a kernel maintainer for Redhat on RHEL (which Centos
is a free version) from 2011 - 2019.  This is addition to writing and
maintaining Squashfs in the upstream kernel.
