using Oracle Linux 9 as a proxy yum server for OL7, 8 and 9
Is it possible to use Oracle Linux 9 (or really does it even matter what version I use) to host internal mirror copies of yum repositories for purposes of patching multiple environments from the exact same set of patches?
I know how to set up a repo on OL7 and OL8 separately, but struggle a bit to figure out how to patch the hosting server against itself while the other clients will be coming in to patch lower versions of the OS. If this is feasible, is there any documentation or examples where this is done? I'm having a hard time with the googler so far finding any example of this.
