Hi Mantas, thanks for the hint. I will try this. I remember that SysRq was once always enabled? It now seems to be disabled in current Fedora releases. I think enabling F key should be default. At least it shouldn't be possbile to do something bad with it, or is it? > > -- > Mantas Mikulėnas <graw...@gmail.com> _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
