elogind participates in dependency loops relevant to architecture
bootstrap. Instead of looking into such a difficult problem, I looked
for easily droppable dependencies:
 * libblkid-dev and libmount-dev are mentioned in multiple meson files
   as not needed by elogind. They can be dropped with no replacement.
 * dbus and libglib2.0-dev are used in unit tests only. They can be
   annotated <!nocheck>.

Please consider applying the attached patch.

Helmut

Helmut,

Thanks for this.

In elogind README.md, libblkid-dev is indeed said to be optional, however
libmount-dev is listed as compulsory and in your patch you have kept it in.

Good idea. Thanks.

Mark

I believe the README.md is outdated here. If you read the sources,
you'll see that it is indeed never used. Thanks for spotting the missing
libmount-dev removal.

If in doubt, I suggest that you build elogind normally, then turn
libmount-dev and libblkid-dev into Build-Conflicts without changing
debian/changelog. If you build such a modified package, you'll observe
that the resulting .debs are bit-identical to the previous once since
elogind is normally reproducible. That should be quite a strong clue,
no?

Helmut

Many thanks for this.

Queued for the next upload.
