Hi,
What if we rename libelogind0 to libsystemd0 with a higher version number
than debian's (same for the dev packages) and make libelogind0 a metapackage
that sucks them in. Would this allow to build the debian packages or are
the libelogind0-dev headers not sufficient to do so?
Just my 2 cents as i'm not a apt/dpkg guru.

Ciao,
Tito
