Description Robert Marcano 2020-11-17 12:48:32 UTC
Tracking bug for packager for upstream bug

The kernel documentation states:

Note that the value of ``/proc/sys/kernel/sysrq`` influences only the invocation
via a keyboard. Invocation of any operation via ``/proc/sysrq-trigger`` is
always allowed (by a user with admin privileges).

So there is no need to change the value in order to trigger sysrq programatically.

This is causing problems on Fedora where the default value of the setting is 16 at /usr/lib/sysctl.d/50-default.conf and low-memory-monitor is changing it to 80 (enabling the 64 bit).
