[arch-general] syslog-ng depends on systemd?
Hi, with the recent update of syslog-ng (3.3.6-2), systemd has been added as a dependency. I though systemd providing its own logging and syslog-ng wasn't needed. Then why is systemd needed for syslog-ng to run? As far i can see from the diffs, nothing has changed apart from adding systemd as a dependency.

Look in syslog-ng.conf: unix-dgram("/run/systemd/journal/syslog"); That means, in its default configuration it requires systemd.

So you had been modifying it to work with initscripts? I see in syslog-ng's changelog that it tries to detect systemd at buildtime and creates the conf file accordingly. So basically it just tries to play nice with systemd and doesn't really require it.

Well that, and the linker seems to want systemd as well: $ objdump -p /usr/lib/syslog-ng/libafsocket.so | grep NEEDED NEEDED libsyslog-ng-3.3.6.so NEEDED libsyslog-ng-crypto.so NEEDED libssl.so.1.0.0 NEEDED libcrypto.so.1.0.0 NEEDED libsystemd-daemon.so.0 <-- o hai NEEDED libpthread.so.0 NEEDED libc.so.6 d

No. Arch had been shipping a config file which didn't know about systemd's socket until about two days ago. Now the arch default has changed. I am not sure what was the vanilla syslog-ng.conf.

AFAIU when syslog-ng is compiled on a systemd-based machine, it will link to libsystemd-*.so by default. So, systemd is required unless disabled explicitly at buildtime. The config file is simply a text file which by itself doesn't justify a dependency on anything. In any case, all arch setups now carry full installation of systemd, so this dependency is not a problem. However, weren't there some rules which tell to not specify dependecies if they are in the base group (systemd will be in base, right)? Like for example, core/which can be replaced by a shell bultin type which is more informative IMHO. But if you remove which lots of things will silently break. -- Leonid Isaev GnuPG key: 0x164B5A6D Fingerprint: C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D
