We are converting from CentOS to AlmaLinux, but noticed that AlmaLinux versions
are just 8.5, where CentOS adopted the idea of an extra qualifier representing a
"level" within the version
For example in CentOS 8, you see:
CentOS Linux release 8.5.2111
The extra qualifier is not a level, but represents the date of the release of code from upstream to CentOS and the build process going on (21 -> 2021, 11 -> November). That worked ok for CentOS because it has a solid date/timeline from Red Hat to do this. Alma and Rocky really don't have such and while it was nice, it seems to break various compliance checkers and such which only expect the Red Hat lower number. [The lack of it probably also breaks sites which expect it there for rebuilds.]
