Preserve customized /etc/sysctl.conf?

[ar-jan]

Would it be possible to preserve customizations to /etc/sysctl.conf? I need the option kernel.unprivileged_userns_clone = 1 for software I'm running alongside BOA, but when I just add this line the change is overwritten by BOA.

I am running quite a few softwares alongside BOA on the same server and a lot of config files get overwritten on an update. My solultion was to write a small script that I launch once BOA finishes upgrading and that script fixes all the settings I desire to keep "my way".

BOA has a long list of control files (or config variables) which can be used to avoid overwriting some files on every upgrade: https://github.com/omega8cc/boa/blob/master/docs/ctrl/system.ctrl#L48

Let's add something also for /etc/sysctl.conf

Done!

Great, thanks!

Note to self (and possibly others): this could actually also have been achieved by placing this option in a file in /etc/sysctl.d/, since Debian supports this.
