Thanks for this.

AFAIU this is not required. We no longer need to fork and patch to remove
libpam-systemd dependencies as Devuan's libpam-elogind provides that dependency.

IIRC this was discussed a few weeks ago and you can use the Debian buster udisks
directly in beowulf. It was tried a few weeks ago, but perhaps you could confirm
that still works and works for you in mate?

The separate, but related question is whether we maintain a forked udisks to
completely remove the logind dependency. THis was discussed at the meet on 11
September, but I am not aware of a consensus or decision.

My opinion, which is based on the least work required and reducing the number of
forked packages to maintain, would be to remove our forked versions from beowulf
and ceres and just use Debian's packages. But that will pull in elogind for all
users of udisks, which may not suit everyone.

Yes it does.

We don't need #923387 fixed for Devuan as libpam-elogind provides libpam-systemd
(this is not true in Debian).
