Thank you for the pointer.

The do-release-upgrade only offers /dev/sda and /dev/sdb. Assumed it's
installed to the root fs (?partition of the root fs?), then a
do-release-upgrade recognises this?

That at least would be a good workaround, IMO still the better solution
would be, if Ubuntu would stop enforcing installing a bootloader.
