Who says it does not?

Interresting. Really. How did you managed install clamav-daemon without
libsystemd0?

The official way of running a system post wheezy without systemd is to install
sysvinit-core. You can remove some of the systemd packages then. libsystemd0
is one of the packages that can be pulled in by others but do no harm. It has
to stay.

I just booted my jessie-amd64 kvm, installed sysvinit-core and clamav-daemon
and removed the systemd package. From my quick test everything works as
expected.

If you remove libsystemd0 apt wants to remove bsdutils as well. How did you
workaround this? From here it looks like you run a broken setup.

If you come up with something that is broken in the official setup (that is as
describned +sysvinit-core -systemd) then we will look into this. If this
remains about "I don't want anything on my system that contains a systemd
string" then I *will* close this bug and you can complain about this one level
higher.
