I recently had a rt kernel wiped on a raspi, which kills linuxcnc. I pulled the sd card in here, and replaced the missing kernel, then following the pin instructions, and then watching the --upgradable listings, added 2 more stanza's to a file in /etc/apt/preferences.d, named kernel.pref, so it looks like this: pi@picncsheldon:~/linuxcnc/configs/sheldon-lathe $ cat /etc/apt/preferences.d/kernel.pref ============================ Package:linux-kernel pin: version 4.4.4-rt9-v7+ Pin-Priority: 1001 Package: linux-headers Pin: version 4.4.4-rt9-v7+ Pin-Priority: 1001 Package: raspberrypi-bootloader Pin: version 1.20170427-1 Pin-Priority: 1001 Package: raspberrypi-kernel Pin: version 1.20170427-1 Pin-Priority: 1001 ============================ pi@picncsheldon:~/linuxcnc/configs/sheldon-lathe $ I know, that is an older rt kernel, but the performance of the newer ones is horrifying, missing keyboard events to the point of completely unusable. > I suppose one could manually mark each and every single installed > package as "manually installed", but you'd have to remember to repeat > this periodically, and it seems clumsy and inelegant compared to some > sort of master switch that can just tell autoremove to go die in a > fire.
