Bug#992711: debhelper: Please provide backport for bullseye

[Niels Thykier]

Hi systemd maintainers,

I have been asked to backport debhelper to bullseye-backports.

Before I do that, I would like to confirm whether this is sake to
backport for people upgrading from oldstable (+backports) to buster
(+backports)[1].
  As I understand it, support for "usr/lib/systemd/system" was added in
buster and the upgrade would have the systemd from oldstable running
(not to mention the helper scripts used in maintscripts - but that might
be solvable with a Pre-Depends).

Can you help understand that situation and what is needed to make it
safe (or confirm that it cannot be done safely).


Thanks,
~Niels

[1] As in people upgrading directly into buster with backports.  It is
safe if people upgrade to buster first, reboot and then add backports
later as far as I understand the situation.
