Hi Ludovic, list,

Correct.

This is not quite correct. You can tell dpkg to --path-exclude files
that match a glob pattern. See `man dpkg` for details. Putting this
in your /etc/dpkg.cfg will make sure all dpkg invocations use it, apt
included.

So, adding for example

path-exclude = /lib/systemd/*

would keep prevent installation of any matching files that a *.deb would
otherwise install. You still have to clean up existing matching files
yourself of course.

So for those of you hell-bent on keeping files reeking of systemd off of
your systems, you can and you can do this yourselves. If it happens to
break stuff, you get to keep the pieces but I guess mentioning breakage
here on the list will certainly peek some people's attention.

Forking all packages that provide files you can easily prevent from
getting installed yourself is indeed beyond the scope of de Devuan
project if you ask me. There's plenty of other stuff to be done.

I've found them to waste disk space on the one hand and provide useful
info to fix issues on the other. Your experience may vary.

As I mentioned in a previous post, I found that rsyslog and the use of
LVM have a dependency on libsystemd0. That dependency can be satisfied
by installing libelogind0 instead of it.

Hope this helps,
