Also see #61090 and #61122.

@dmitshur Thanks. Is there anything I could do to help get these LUCI builders up for openbsd? I have to admit that I don't know much about LUCI builders at all, but it appears that we are discontinuing the old builders so we need to get this sorted at some point.

[dmitshur]

Yes, you can find more context on the builder migration to LUCI in #63471 (and in #60468), and especially in the https://go.dev/wiki/DashboardBuilders#luci-builders page it links to.

For openbsd/amd64, there's already a builder in LUCI that uses the "openbsd-amd64-72" image (#61090), so I think this would be mostly a matter of creating equivalent "openbsd-amd64-7{3,4}" images, and configuring them in LUCI. That is, the equivalent of CL 535755, but in the luci-config branch of x/build. We'll have to sort out the exact details since this might be the first OS update we're doing for an existing LUCI builder.

For openbsd/386, the LUCI builder and its image still need to be built (#61122), so this could be a good starting point. Again, start at #63471 and try to follow the directions there, and post on the issue as you make progress.

Thanks for your help with moving these builders forward.

OpenBSD 7.3 and 7.4 are no longer supported releases, closing in favour of #69823

Marking this as "not planned" so the issue outcome is more visible at a high level.
