Why do mpd/dbus/probably others depend on systemd

> mpd
mpd: error while loading shared libraries: libsystemd-daemon.so.0: cannot open shared object file: No such file or directory

If you compile it from ABS it works fine, so this seems entirely pointless. Can the official repos be upgraded to have binaries that run without systemd?

Re: Why do mpd/dbus/probably others depend on systemd

systemd provides functionality that some people desire and other people don't. Either way, SOME version is going to end up in the AUR. And there's nothing wrong with that. It's just the AUR.

If you have a technical reason why you feel the dependencies for mpd should be changed, then please file a bug report on the Arch Linux bug tracker.

What is the difference between mpd compiled with and without systemd?

Re: Why do mpd/dbus/probably others depend on systemd

One is compiled with systemd and the other without? I feel like that might have been a trick question…

All the best,

Re: Why do mpd/dbus/probably others depend on systemd

I think I may have misunderstood your original post...

I just took a look at the PKGBUILD for mpd. It doesn't depend on systemd, although something mpd does depend on might, I don't know.

As far as I can tell (which isn't far), mpd just provides a file that allows the mpd daemon to be started with systemd.

Re: Why do mpd/dbus/probably others depend on systemd

Technically, it doesn't depend on systemd

Depends On     : libao  ffmpeg  libmodplug  audiofile  libshout  libmad  curl  faad2  sqlite  jack  libmms  wavpack  avahi  libid3tag  yajl

rather it requires systemd to run. Not trying to be pedantic; maybe it needs to depend on systemd. Or do we not do that since systemd is the init system?

If mpd doesn't depend on systemd itself but crashes without it, this is - in theory - worth a bug report. In practice it doesn't matter much because you are expected to have systemd installed anyway.

It would be nice to know what hhhhhh actually tries to accomplish, because running an Arch installation without systemd even being installed sounds kind of insane to me.

Re: Why do mpd/dbus/probably others depend on systemd

mpd links against libsystemd-daemon to provide socket activation. If you really want to remove systemd, create a separate (tiny) libsystemd package with /usr/lib/libsystemd-daemon.so*. Without systemd installed, this library does nothing.

Systemd is part of the core that makes up Arch Linux. It provides udev, is used as PID 1, manages services, handles login sessions and probably lots of other stuff that I can't think of right now. It is assumed that you have it installed, and is the only officially supported init system at the present time.

Why would official Arch packages be compiled without it?

I compiled an empty shared library and put it here and it didn't fix it so I assume that's not what you mean. Please can you explain again?

Why would they be when all it does is break packages for people not using systemd...

Because systemd is assumed to be installed and if software can provide more functionality with systemd, it makes perfect sense to make use if this. If you are actually brave enough to uninstall systemd on an Arch installation, you are in the minority (the very, very small minority) and have to deal with this yourself by recompiling everything from the ABS.
