Sorry, I see this message only today.

I suppose the real command is "sudo-rs", and "sudo" is an
alias/symlink/whatever.

For now, I think jhalfs will keep requiring the original sudo. That's
just the same as requiring docbook-4.5 or bash and not dash, etc. Maybe
a little restrictive, but nothing that cannot be easily solved. Of
course some tricks have to be known for specific distros (like the
"dpkg-reconfigure bash" that allows sh to be a symlink to bash instead
of dash on debian and ubuntu...). And blfs installs original sudo
anyway.

The commands you propose seem a little complicated. A normal
installation of ubuntu is not in a container. The normal command for
using original sudo is:
update-alternatives --set sudo /usr/bin/sudo.ws

(not sure why there is this ".ws" extension)
