That's very interesting. Devuan's dbus shouldn't depend on
libsystemd0 at all (it builds and runs without it); if it is pulling
in libsystemd0 as a dependency, then there's a bug in our dbus package.
Can you show me the output of:
$ aptitude show dbus
$ apt-cache rdepends dbus
Also, if it is convenient, can you download (but not install) dbus,
extract the package, and run "ldd" on dbus-daemon to see whether or
not the binary accidentally got compiled to link against libsystemd0?
Thanks,

Hello Jude,
I am not sure what you are trying to understand. I think "aptitude show
dbus" only provides the information on dbus package that is currently
installed. As I am using dbus package from http://angband.pl/debian/,
which clearly does not have dependency to libsystemd0, so the result is
not as you expected. Anyway, I collected the outputs that might be
relevant, a part from "apt-cache rdepends dbus" as this one provides the
list of packages that depend on dbus so I got a long list and none of
them is libsystemd0. I think the output of "ldd usr/bin/dbus-daemon"
below confirmed that dbus package on Devuan repository requires libsystemd0.
Based on the my experience so far in fighting to remove systemd
components from Debian, I think the easiest and certain way to know the
dependency that comes from the repository that we pull in is by running
"apt-get -u dist-upgrade" and hit "n", then manually check why systemd
components are being pulled by running "apt-cache depends <list of
packages>".
Kind regards,
Anto

Description: simple interprocess messaging system (daemon and utilities)
D-Bus is a message bus, used for sending messages between
applications. Conceptually, it fits somewhere in between raw sockets and
CORBA in terms of complexity.
D-Bus supports broadcast messages, asynchronous messages (thus
decreasing latency), authentication, and more. It is designed to be
low-overhead; messages are sent using a binary protocol,
not using XML. D-Bus also supports a method call mapping for its
messages, but it is not required; this makes using the system quite simple.
It comes with several bindings, including GLib, Python, Qt and Java.
This package contains the D-Bus daemon and related utilities.
The client-side library can be found in the libdbus-1-3 package, as it
is no longer contained in this package.
