Those sound like good arguments, but if we don't test on older releases then we don't know for sure they work either. IMHO it's acceptable to explicitly only support EL 7.4 and up. We don't have the resources to support older versions especially since CentOS doesn't support that either. If users want verified working versions on EL < 7.4 then they should either help us properly support it or buy support from a vendor that does want to promise it works.

I would be against syncing regularly but I don't do much packaging so
it's up to you. The problem I see is "random" breakage. You come to
work on Monday after sync and if you don't realize the package was
deleted from EPEL, you can burn hour or something to figure it out
sometimes. This was pretty clear case but as you know there are
situations (SCL) when it is not that clear.

If we ever deploy new koji, I'd vote to avoid getting OS updates
completely, just base channels and explicit updates when we need it.
We need reproducible builds, with autosync we are not getting it.

One note, if we sync CentOS or RHEL base to particular version,
chances are that SELinux won't load on older releases. So basically we
must be ready to do minimum requirements change here.

Thanks for solving the problem.

I think we should sync & update. CentOS has no concept of supported minor
releases and we should be testing with a supported release.

This now appears to be working again. One out standing question that
affects nodejs- packaging builds.

As part of the RHEL 7.4 release, http-parser was removed from EPEL. With
this latest round of Koji external repositories update we now have a newer
EPEL with this package removed. We did not update our CentOS external
repository that would include this package. Not updating the base OS has
been our policy for a while now it would seem. We have two options:

1) Sync and update CentOS
2) Add http-parser to the overrides tag for foreman-nightly

I had forgotten to run the repo-regen on Koji. That is finishing up now.
I
will run another test after and report back.

I might not have, this path DOES have repodata:
