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.

I get semver: x.y.z, but in the context of distribution packages (never upstream releases), I often see versions like 5.2.1-1, what does the extra number mean?

You kind of answered your own question. The stuff after the dash references different manifests or builds of the same software into whatever package system.

It might mean they screwed up the hashes or added an extra platform specific patch to make the package.
