libsystemd0 is, as I've been told, a library that provides the
interfaces provided by systemd without the content. For example,
a typical systemd feature will, as implemented in libsystemd0,
merely report back in the proper manner, that the facility requested
is not available.

As such is it harmless, but allows programs that have only incidental
delendency on systemd to function properly when run without it.

A program can test whether it it running on a systemd system or not
and act properly on either kind of system.
