sysctl items not persisting after reboot on Ubuntu 20.04

[Aaron Jones]

What is the name of the sysctl files? You may want to try renaming them something like zzz-mysysctlstuff.conf to make sure they aren’t being over written to start? Or are they already named high enough in the order so it’s a moot point?
