Subject: apt: Unexpected linkage dependency on libsystemd

Package: apt
Version: 1.8.2
Severity: normal

I observed a linkage dependency on libsystemd. This was unexpected for me
since I wouldn't expect a package manager depend on it. A package manager should
be as lean as possible.

Having reviewed the code, the only function using libsystemd is used to talk on dbus 
to inhibit system shutdown. Something which will work for systemd only.

Would it make sense to use dlopen() to dynamically load libsystemd when needed
and avoid the hard dependency on libsystemd? If systemd is installed, libsystemd
will be available anyways.
