From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Kinda tired of the constant flow of endless "analysis" of xz at this point.
There's no real good solution to "upstream gets owned by evil nation state maintainer" - especially when they run it in multi-year op.
It simply doesn't matter what downstream does if the upstream build systems get owned without anyone noticing. We're fucked.
Debian's build chroots were running Sid - so they stopped it all. They analyzed and there was some work done with reproducible builds (which is a good idea for distro maintainers). Pushing out security updates when you don't trust your build system is silly. Yeah, fast security updates are nice, but it took multiple days to reverse the exploit, this wasn't easy.
Bottom line, don't run bleeding edge distros in prod.
We got very lucky with xz. We might not be as lucky with the next one (or the ones in the past).
Or the ones in the present, for what that’s worth
