[Michael Biebl]

Ben, you just closed the bug again. I assume this was by accident?

The downside of this approach obviously is, that as soon as you switch
kernels (e.g. use a self-compiled one), this setting changes.
So explicitly setting the sysrq key imho has benefits.

Do you remember, why you decided against using a sysctl.d snippet?

Let me also add, that custom modifications, if done via /etc/sysctl.conf
should be preserved, i.e. once [1] is fixed

Do you also happen to remember where this discussion happened so we have
some reference for this bug report.
