Does that mean .NET 7 on arm64 will no longer be supported on RHEL 8?

Good call. That isn't the intention.

This is probably the "what do we do when CentOS 7 goes EOL" come early topic. We likely need to target an older glibc. Right?

Yes, RHEL 8 has glibc 2.28.

Is there a recommended pattern on how to do that?

Here are two examples:

• Tensorflow (use modern OS; download foreign old glibc to use at compile-time)
• Python manylinux (build in docker with old OS)

Do we consider RHEL8 as "modern OS"?. If so, we could use it as base line. That would make it more similar to x64.

We're in the process of switching (for .NET 7+) of using Mariner as our build host. That likely means that we'll need to acquire a foreign glibc to compile with, much like the Tensorflow model, but in a consistent container image, like the Python manylinux model.
