..we used to have a "--what-provides" search flag somewhere,
man -k, man dpkg-query, man apt-file, man apt-cache etc did
not turn up anything ringing any bells for me, so I tried:
https://packages.debian.org/search?searchon=contents&keywords=systemd-logind&mode=filename&suite=unstable&arch=any ?

..I like this a lot better: http://wiki.grml.org/doku.php?id=debian

..can we trust these anymore?
https://packages.debian.org , http://packages.ubuntu.com/ and
https://www.debian.org/doc/debian-policy/ch-relationships.html
https://www.debian.org/doc/manuals/debian-faq/ch-pkg_basics.en.html

Scenarios always come in sets of three:
best case, worst case, and just in case.
