Hi, tried to safely bring down a crashed Fedora 21 machine today, but M-sysrq didn't do anything. After bringing the machine up again, the logs showed that M-sysrq functionality was disabled. After investigating further, it seemed that only Sysrq-S (emergency save) was actually working. In /etc/sysctl.d/01-sysctl.conf, "kernel.sysrq=1" was present. It took me nearly 30 min. to find out that systemd has it's own sysctl definitions, gladly ignoring/overwriting /etc/sysctl.d. In /usr/lib/sysctl.d/50-default.conf, "kernel.sysrq=16" was set, which is what crippled full sysrq functionality.
In addition, I'm curious what happens when the next systemd update gets pulled in. Most probably, my manual settings will be overwritten with what systemd thinks is good for the user.. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
