With my face pasted against the window. After a while, all those tiny clouds look like a field of sheep 💤

A towel

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@feddit.de 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.

Not really, I’m not new to containers.

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.

On bare metal, no containers, no rebooting.

Transhumanist, non-practicing Antitheist

Raised Roman Catholic, broke with that after a classmate died out of the blue of an aneurysm (how could God let shit like that happen?), after looking through Buddhism and some Occultist stuff, realized that the main function of “God” is to be used as a prop to scam people. I’ve considered the Satanist Left Hand path, but I don’t care about rituals. I’d rather follow the scientific method as applied to everything, and use it to extend and expand human nature. While theists still kind of nauseate me with a dash of pity, like seeing a dead kitten in the gutter, I’m up for positive interactions with anyone capable of maintaining one.

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.

Could you link some examples?

Also keep in mind that people can release their work under multiple licenses, so they may upload the same work with a different license (like a privative one) to other markets.

Just saying, not everyone needs session management…

“do one thing well”

Arguably, Systemd does exactly that: orchestrate the parallel starting of services, and do it well.

The problem with init.d and sys.v is they were not designed for multi-core systems where multiple services can start at once, and had no concept of which service depended on which, other than a lineal “this before that”. Over the years, they got extended with very dirty hacks and tons of support functions that were not consistent between distributions, and still barely functional.

Systemd cleaned all of that up, added parallel starting taking into account service dependencies, which meant adding an enhanced journaling system to pull status responses from multiple services at once, same for pulling device updates, and security and isolation configs.

It’s really the minimum that can be done (well) for a parallel start system.
