what you ask is Debian what you need is FreeBSD

For exemple

16/8 is the most common intermittent fasting protocol for begginers. 20/4 is recommended in case of autoimmune disease, to reverse leaky gut and insulin resistance.

Actually, science says he’s right. You should fast at least 16 hour per day.

Bla bla bla, so much energy to just not give what I ask for.

Those are not “details”, but “blur sources”.

You can check LXD too : https://wiki.archlinux.org/title/LXD And podman : https://podman.io/ Podman is docker without dockerd, and is more similar to what is bastillebsd to jails. https://bastillebsd.org/

“Blue is the absolute color” … why ?

I had a really bad experience with NixOS, the idea is great, but I had a lot of troubles at each generation switch. I don’t like it because I had to learn a lot of specific tools, that only applies on that OS, and it was (really.) hard. I prefer a classic distro, maybe Debian (or Freebsd if not linux), with Ansible for declarative config, and ZFS storage to be able to revert a snapshot if I have any kind of problem.
