For example, I’m using Debian, and I think we could learn a thing or two from Mint about how to make it “friendlier” for new users. I often see Mint recommended to new users, but rarely Debian, which has a goal to be “the universal operating system”.
I also think we could learn website design from… looks at notes …everyone else.
There are many steps that need to be followed, I didnt have the time yet but it is possible. You need to sign the modules and kernel, package as an RPM, sign that maybe etc. Its not as easy if you do it right but also not very hard.
