Hi,
What would be the steps needed to source build this, under community supported OS like FreeBSD, for which we are doing builds?
Like getting preview-1 to build took some effort, I was thinking, that with next preview, it could just use previous preview, but that's not the case. While building preview-2 using preview-1 sdk and artifacts, I hit:

Any tips on how to resolve this?

This is because Preview 2 requires re-bootstrapping. This is called out in the additional release notes.

Yes I saw that, maybe silly question, but how to do this? :)

You would have to build P2 just like you did P1. More details at https://github.com/dotnet/source-build/blob/main/Documentation/bootstrapping-guidelines.md
