Description Michał Górny 2013-08-05 13:04:59 UTC

systemd-sysctl ignores duplicate assignments currently. For example, on my initial solution this triggered:

$ /usr/lib/systemd/systemd-sysctl 
Duplicate assignment of kernel/sysrq in file '/etc/sysctl.d/99-sysrq.conf', ignoring.

But in effect, this makes the 'override' order of sysctl.d files completely reverse. That is, if you set the same key in '10-foo.conf' and '50-foo.conf', the value from '10-foo.conf' would be applied rather than '50-foo.conf' as you'd expect.

I just ran into the exact same issue. I want to set kernel.sysrq=1 overriding the value from /usr/lib/sysctl.d/50-default.conf but because of the duplicate assignment restriction my only choice is to copy the supplied file to /etc/sysctl.d and modify it there. But then I will lose all future updates that systemd is going to do in /usr/lib/sysctl.d/50-default.conf.

You can also set it in /etc/sysctl.conf which overrides everything else.

Commit 04bf3c1a [1] contains a fix for that issue so hopefully this will be fixed in systemd-207. I tried it with the gentoo live ebuild and it works.

Closing then.
