Release package - All PR's should be against staging/src/rocky-release

Notes for Packagers/Builders

This package can produce multiple variants of rocky-release:

• Stable: rocky-release, rocky-repos, rocky-gpg-keys, etc

• LookAhead: All packages appended with -lookahead

• Beta: All packages appended with -beta

• If --with=rllookahead or --with=rlbeta are set in mock, those variants are built

• If both are set the same time, build will fail

When --with=rllookahead is set the minor version will typically be y+1. So if the current stable is X.0, the next would be X.1.

For pre-releases/beta, both packages should produce X.Y until changed in the spec.

The rllh macro may be versioned out for future use. It does not have to be explicitly set.

A rllh_minor macro may be introduced in the future.

How does this benefit us?

It provides an opportunity to do self testing of various kinds. In most cases, a rocky-release package for the upcoming minor release will be built normally and doesn't require the variant release packages. However, the option is at least available for those who want to test something in particular and override the default rocky-release packages.

What is the rloverride macro?

This simply sets the dist tag to .el%{major}.override and changes the ID="..." tag in /etc/os-release to read as rhel rather than rocky. This helps us perform very specific builds that cannot otherwise be debranded properly, eg dotnet. This should also change the initial macros to only provide %rhel and not CentOS or any other derivative macro name, as some packages specifically look for these macros being set as well and also applies to those packages that cannot be properly debranded or when debranding has not visual or functional benefit.
