You can, however, configure Linux to automatically reboot on a kernel panic by making a small modification to /etc/sysctl.conf, a configuration file that tweaks many kernel operating parameters.

With Linux 4.0, we're one step closer to the version of Linux used by the T-800 Terminator. But it's full of handy improvements!
