I've been running a Samba DC and a Samba file server, both in separate
containers (ordinary LXC's) as well as a Windows KVM client, for
several years (since Debian Stretch) on the same Debian host at two
different sites.

No issues except the fear of upgrading - that is if I upgrade the host
will my containers and vm keep running (will a dist upgrade from
"Stretch", to "Buster", to "Bullseye", to "Bookworm" continue to
support the older containers and vm), or how far can I upgrade the
containers without upgrading the host (assuming at some point a
"Bookworm" container may need something newer than a "Stretch"
kernel).
And is there a proper order in which to begin such upgrades. Questions
I haven't seen answered anywhere. If anyone knows please advise.
