systemd-logind.h pops up in the xorg-server source (a lot):

root@sybilla:/usr/src/xorg-server-1.19.2# egrep -R systemd *
 ...
hw/xfree86/common/xf86Init.c:#include "systemd-logind.h"
hw/xfree86/common/xf86Init.c:        systemd_logind_init();
hw/xfree86/common/xf86Init.c:    systemd_logind_fini();
 ...

but apparently it might still be possible to rebuild xorg without:

root@sybilla:/usr/src/xorg-server-1.19.2# head -n 13 debian/rules 
#!/usr/bin/make -f

ifeq ($(DEB_HOST_ARCH_OS), linux)
	selinux        = --enable-xselinux
	wayland        = --enable-xwayland
	logind         = --enable-systemd-logind
	systemd-daemon = --with-systemd-daemon
else
	selinux        = --disable-xselinux
	wayland        = --disable-xwayland
	logind         = --disable-systemd-logind
	systemd-daemon = --without-systemd-daemon
endif

I may have a go at this later this week (just to see what i can break ofcourse).

You might want to read this. It doesn't answer your specific question but it will help you understand why some (non-functional) systemd files may be on your computer. If someone has the time and skill all those unsightly (but non-functional) deps could be removed from the offending apps and be repackaged.

I used the suggested command several times (i guess it only finds a few deps each time) and was able to remove stuff until it returned this:

$ aptitude why libsystemd0
i   xserver-xorg-video-radeon Depends xserver-xorg-core (>= 2:1.18.99.901)
iBA xserver-xorg-core         Depends libsystemd0

Are the xorg libs really dependent on systemd?

Is there a way to do this if you don't have aptitude installed? I don't see a similar apt command....

Not exactly the same, but it lists packages that depend on lsd0:

apt-cache rdepends libsystemd0

You may have to chase down some dependency trails until you recognize something that you know is installed.

libpulse0 gets dragged in with some of the media programs, VLC will do it. My basic understanding from the documentation is that it's just there to translate if you are on a network and trying to deal with another machine that uses pulseaudio. In practice though it will dump a pulsecookie on you and make itself at home in your Home. I left part of it since VLC wants it but de-fanged it so it doesn't poop out pulsecookies every session.

It looks like qemu was compiled with pulseaudio support, that's going to be the case with most Debian packages.

All very simple in your case however - getting rid of qemu would enable you to remove libpulse0 and libsystemd0.

However, as you've guessed, those libs don't do a whole lot on their own. If you have pulseaudio installed however, libpulse0 is of some use. libsystemd0 however is cruft without systemd installed.

Ha! Wasn't expecting this!

$ aptitude why libpulse0
i   qemu-system-x86 Depends libpulse0 (>= 0.99.1)

Do the same for libpulse0.

Re: (SOLVED) Systemd Library in Ascii

dummy@example.com (golinux) — Wed, 01 Nov 2017 16:17:32 +0000

$ aptitude why libsystemd0
i   libpulse0 Depends libsystemd0

I think that vlc might need that. pulseaudio is not installed. But that's on jessie and Lydia_K cleared out most systemd deps. Rinse and repeat needed for ascii

If you've found it installed, that would suggest that it is in fact installed.

I have this library installed in Devuan Ascii.

libsystemd0:amd64

Are these components still in devuan?
