Hello,

On order to be able to install mate-desktop-environment in Debian (and maybe
other desktops) udisks2 is needed. Currently udisks2 depends on libpam-systemd
and build-depends on libsystemd-dev. The attached patch for version 2.8.4-1
fixes the build, as reported in #923387. Additionally, creating a link in
libelogind-dev:
/usr/lib/x86_64-linux-gnu/pkgconfig/libelogind.pc-> libsystemd.pc
(and s/x86-linux-gnu/triplet/ for other architectures.)
enables the usage of the login option:
using libsystemd-login:     yes

Unfortunately I don't know how to test if it works with elogind. Anybody knows?
Anyway, I do have mate running on a real Debian GNU/Linux laptop now!

After a new release of elogind the Build-Depends condition on libelogind-dev
(>=241.3-1+debian1) in debian/control should be upgraded accordingly.

I know we really have problems getting the patch in #923387 applied. However,
creating an updated version of elogind (now 241.3-1+debian1) followed by an
updated patch to udisks2/debian/control would at least make it possible to
install elogind and manually build udisks2 with the patch in that bug report.

Alternately, creating an updated version of udisks2 for Devuan/Beowulf would be
nice (and doable). Looking at the packages for Devuan they are outdated:
ascii: 2.1.8-1+devuan2
beowulf: 2.1.3-5+devuan2
ceres: 2.1.3-5+devuan2
experimental: 2.6.5-2+devuan1

@Mark, are you interested?

Thanks!
