@a-gave Should I be replacing the antennine entry in the owut docs with this, or do they serve different audiences?

Yes it should be replaced with the new official instance of libremesh.
Actually https://sysupgrade.antennine.org is a backup server with official asu installed with feeds from libremesh enabled, it runs on a vps with 4 vcpu cores 8GB ram.
There is a second instance with my fork in an homelab https://syupgrade-01.antennine.org, 4cores 8GB ram. We plan to keep at least one of them as backup, because it is very convenient to have a server that pulls imagebuilders and build without having a local build environment.
