I wish it would that simple for practical use cases.
I ship professional software for colorists for Hollywood studios and they absolutely love to never upgrade. We have to ship for RockyLinux 8. Sad.
>Rocky Linux 8 is supported by the Rocky Linux project until May 2029.
Just the other day I tried running an older binary and it failed with a glibc error, despite it being linked to a glibc version that's barely 5 releases behind the one on my system. So maybe glibc isn't backwards compatible after all...
