Hi, first off thanks for the great tool! I currently rely on a systemd unit file present in the Fedora package for powertop to do most of my laptop's power saving config on boot, and it works great. However, I've noticed a missing tunable which might be helpful for some folks: setting the kernel.core_pattern sysctl parameter to |/dev/null or similar. On my x220, this parameter set to it's default causes systemd-coredump to peg a single core, sometimes for quite an extended period of time. On many devices this would cause substantially greater heat output, and most importantly substantially higher power consumption. I had a quick browse of the source code to see if this addition was trivial enough for me to submit a patch over, but from what I could see the existing tunables seem to work exclusively with sysfs. Unfortunately I don't write much C++, so I apologise for sending this particular email rather than submitting a patch for y'all. Thanks
