I think we should add dedicated builds and nFPM steps for AIX, instead of including it in the existing builds and nFPM. Specifically, I think we should avoid building deb packages.

This doesn't even create AIX packages currently, as it is not currently supported by nfpm. I have open issues to have support added. I just wanted to be ahead of it.

Once/if it is supported, it would only build rpm packages anyway, just like it only builds an msi for Windows. Seems like a lot of unneeded duplication of code to me, making it harder to maintain.

AIX differs enough, it might be benefit from its own pre and post scripts instead of expanding on the Linux scripts. This would allow us to focus on testing AIX instead of looking for regression on linux, with respect to the script changes.

That would be easy enough to do, but the changes are so simple, is it truly worth it? These scripts in general are super simple.

Since the rpm portion doesn't currently work, I've restored the pre/post install scripts to what we had before. We can deal with that if the nfpm tooling adds AIX support.

@Dylan-M we should remove Corbin from this PR, if you can.

@jsirianni We aren't going to be able to vet the list of receivers any deeper than we currently have due to expanded list of customers potentially needing it.

Hey gents, I've just refreshed this PR this morning to bring it up to the current "default" release branch. I know the hardware isn't ready yet (yes, we have an actual Power server now that will run AIX), but I'm trying to be as prepped for that as possible ahead of time.

Were there any outstanding comments that need addressed beforehand? I know we had some discussion around changing some of the scripts to where AIX has its own unique ones instead of shared. Is that still a concern?

No high level concerns here. I'm fine with the script being shared between linux and AIX (it is called install_unix.sh after all).
