He didn’t even want to kill all those people, he only wanted to exploit them and then deport everyone to Africa… but the Allies wouldn’t let him conquer enough Africa for all of them, so what was he to do? Killing then wasn’t even his idea, it was Reinhardt’s! He just signed it…
I know what I said. Linux upholds the “don’t break userspace” contract pretty well: most kernels, particularly those from generalistic distros built with modules, are compatible with whatever userspace binaries you throw at them. Major version changes in glibc (or equivalent) is where incompatibilities start, but those happen quite rarely, and you can often still force multiple glibc versions to run side by side.
What @exi said. Switching .deb based distros is little more than changing sources, maybe some pinning, doing an upgrade, and optionally a cleanup pass to remove any stranglers.
My main Linux box is a Debian-Ubuntu-Debian upgrade, that hasn’t seen a proper reinstall for like 15 years (switched all the hardware several times, still no clean reinstall).
Switching between non-deb distros is also possible, with a chroot. Like, Gentoo to Fedora. As long as the kernel is compatible with the glibc, it’s basically like running containers, just on slightly hard mode.
This might blow yours though: I once booted up from a Tomsrtbt disk, installed Debian, added some RedHat packages, and topped it up with some pinned downgrades from Ubuntu.
Debian would not create and maintain a “core debian” variant just to be installed then receive the extra packages
Debian server minimal, is kind of a “core Debian”. There are netinst versions that can be even smaller. The Debian base image for Docker is even smaller than all that.
There is also an Ubuntu minimal install that you could call “core Ubuntu”.
But more importantly, and I can’t stress this enough: YOU CAN SWITCH DISTROS WITHOUT REINSTALLING. Might need to do some cleanup afterwards, but it’s perfectly doable, more so between Debian based ones.
