Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Been away from Linux for many years
An example of an installable immutable OS is Fedora Silverblue. Notably, you can change the "distro" flavor of Silverblue to try out KDE and then just flip back to Gnome. Each change is seen as an "update" that just moves you over to the new GUI. The article below explains a bit more.

I need something stable in my life...
I guess something like Fedora Silverblue might offer you something (to paraphrase) "stupid proof". For example, in this case the rpm-ostree rollback command would have been sufficient. Disclaimer: rpm-ostree builds images, therefore it's by necessity slower than apt. Futhermore, until this change is merged and deployed you'd have to reboot for the changes to apply. You might want to look into Distrobox as well, perhaps it can solve your problems without having to change your distro.

Nobara is letting me down lately.
However, I'll add one more that I'm especially fond of. It's one of the most 'stable'\1]) Linux desktop systems\2]) without sacrificing access to the latest kernel-updates and packages. It comes bundled with everything\3]) necessary for productivity right out of the box and is built on top of the fundamentals laid by Fedora's Immutable Desktops. Allow me to introduce uBlue; I know that I'll undersell it regardless, so I recommend you to check the provided link instead.

Run0 – systemd based alternative to sudo announced
> 3. even `adduser` will not allow it by default
5. useradd does allow it (as noted in a comment). 6. Local users are not the only source, there things like LDAP and AD.
7. POSIX allows it:

Systemd Rolling Out "run0" As sudo Alternative
> I for one love to type out 13 extra characters
FWIW, systemd is normally pretty good at providing autocomplete suggestions, so even if you don't want to set up an alias you'll probably just have to type `--b ` to set it.
> I wonder what random ASCII escape sequences we can send.
According to the man page source[0]:
> The color specified should be an ANSI X3.64 SGR background color, i.e. strings such as `40`, `41`, …, `47`, `48;2;…`, `48;5;…`
and a link to the relevant Wikipedia page[1]. Given systemd's generally decent track record wrt defects and security issues, and the simplicity of valid colour values, I expect there's a fairly robust parameter verifier in there.
In fact, given the focus on starting the elevated command in a highly controlled environment, I'd expect the colour codes to be output to the originating terminal, not forwarded to the secure pty. That way, the only thing malformed escapes can affect is your own process, which you already have full control over anyway.
(Happy to be shown if that's a mistaken expectation though.)

Linux fu: getting started with systemd

There are some very compelling arguments made there if you care to read them
-
Ubuntu 24.04 (and Debian) removed libsystemd from SSH server dependencies
Maybe it was because you weren't pointing out anything new?
There was a pull request to stop linking libzma to systemd before the attack even took place
https://github.com/systemd/systemd/pull/31550
This was likely one of many things that pushed the attackers to work faster, and forced them into making mistakes.

Systemd minimizing required dependencies for libsystemd
The PR for changing compression libraries to use dlopen() was opened several weeks before the xz-utils backdoor was revealed.

The xz sshd backdoor rabbithole goes quite a bit deeper
I find this the most plausible explanation by far:
* The highly professional outfit simply did not see teknoraver's commit to remove liblzma as standard dependency of systemd build scripts coming.
* The race was on between their compromised code and that commit. They had to win it, with as large a window as possible.
* This caused serious errors.
* The performance regression is __not__ big. It's lucky Andres caught it at all. It's also not necessarily all that simple to remove it. It's not simply a bug in a loop or some such.
* The payload of the 'hack' contains fairly easy ways for the xz hackers to update the payload. They actually used it to remove a real issue where their hackery causes issues with valgrind that might lead to discovering it, and they also used it to release 5.6.1 which rewrites significant chunks; I've as yet not read, nor know of any analysis, as to why they changed so much.
Extra info for those who don't know:
https://github.com/systemd/systemd/commit/3fc72d54132151c131...
That's a commit that changes how liblzma is a dependency of systemd. Not because the author of this commit knew anything was wrong with it. But, pretty much entirely by accident (although removing deps was part of the point of that commit), almost entirely eliminates the value of all those 2 years of hard work.
And that was with the finish line in sight for the xz hackers: On 24 feb 2024, the xz hackers release liblzma 5.6.0 which is the first fully operational compromised version. __12 days later systemd merges a commit that means it won't work__.
So now the race is on. Can they get 5.6.0 integrated into stable releases of major OSes _before_ teknoraver's commit that removes liblzma's status as direct dep of systemd?
I find it plausible that they knew about teknoraver's commit _just before_ Feb 24th 2024 (when liblzma v5.6.0 was released, the first backdoored release), and rushed to release ASAP, before doing the testing you describe. Buoyed by their efforts to add ways to update the payload which they indeed used - March 8th (after teknoraver's commit was accepted) it was used to fix the valgrind issue.
So, no, I don't find this weird, and I don't think the amateurish aspects should be taken as some sort of indication that parts of the outfit were amateuristic. As long as it's plausible that the amateuristic aspects were simply due to time pressure, it sounds like a really bad idea to make assumptions in this regard.
