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.

Arch is on 5.6.1 as of now: https://archlinux.org/packages/core/x86_64/xz/

We at Nixpkgs have barely evaded having it go to a channel used by users and we don't seem to be affected by the backdoor.

Arch had a patch rolled out yesterday [1][2][3] that switches to the git repo. On top of that the logic in the runtime shim and build script modifier was orchestrated to target Debian and RPM build systems and environments [4].
