Most books and courses introduce Linux through shell commands, leaving the kernel as a mysterious black box doing magic behind the scenes. In this post, we will run some experiments to demystify it: the Linux kernel is just a binary that you can build and run.
As said: installing the LTS kernel also works, I think.
And you wouldn’t use Arch for servers, you want something stable (as in “rarely changing”) there.
I wouldn’t use arch for anything.
I really like rolling release. So much better to deal with updates one-by-one than in a giant batch every half year or so.
