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.

Interesting development.
A recent example is that reproducible builds allow for the creation of proof, simply by rebuilding and comparing the result, that a GCC build whose source was extracted with a compromised xz was not compromised; this process was achieved without needing to reverse engineer how the compromise occurred. Similarly, reproducible builds were reported as being usefully during investigations of the xz compromise.
As much as I love openSUSE, and reproducible builds are a core requirement for trusted computing…
reproducible builds were reported as being useful
Really buries the lede of the xz attack results
either both are trojaned, or none
Edit: It is very useful for the first half - to ensure new packages extracted by a compromised xz weren’t modified during the extraction.
It’s just that reproducing the build of the tampered xz would still produce a bit-for-bit identical compromised version due to the way it modified the build system
