If I run
rm -f /var/lib/tor/keys/* 2>&1 >> /home/[me]/reboot.txt
it doesn't error (as long as I run it with sudo) but it also doesn't do anything, checking keys shows it still contains files.
I read the RAM disk tutorial that is linked on the Tor Relay Security page, what I don't understand is how the keys are created and stored solely in RAM. When launching tor for the first time (say "sudo apt-get purge Tor" then "sudo apt-get install Tor") the keys folder does not exist. Would I just mount the whole /var/lib/tor folder in RAM instead or is there a better way to do it?
