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.

Are there any things in Linux that need to be started over from scratch? (lemmy.ca)

I'm curious how software can be created and evolve over time. I'm afraid that at some point, we'll realize there are issues with the software we're using that can only be remedied by massive changes or a complete rewrite.

Are there any instances of this happening? Where something is designed with a flaw that doesn't get realized until much later, necessitating scrapping the whole thing and starting from scratch?

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 lzip tends to do better at compression than xz/lzma and, to paraphrase its manual, it's designed to be a drop-in replacement for gzip and bzip2. It's been around since at least 2009 according to the copyright messages.

That said, xz is 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.
