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.

One might exist already: lzlib.
I admit I haven't done a great deal of research, so maybe there are problems, but I've found that
lziptends to do better at compression thanxz/lzmaand, to paraphrase its manual, it's designed to be a drop-in replacement forgzipandbzip2. It's been around since at least 2009 according to the copyright messages.That said,
xzis going to receive a lot of scrutiny from now on, so maybe it doesn't need replacing. Likewise, anything else that allows random binary blobs into the source repository is going to have the same sort of scrutiny. Is that data really random? Can it be generated by non-obfuscated plain text source code instead? etc. etc.Personally I quite like
zstd, I find it has a pretty decent balance of speed to ratio at each of its levels.
