Thiago's questions would be good to have an elaborated answer on. In
particular, whether BuildStream - which seems like it's only a few
months old - is a core part of the 'API' for the SDK, or whether it's
just incidentally used as part of the build process. I hadn't heard of
it until now, and would be curious to see if it's really used at all
outside of GNOME and Codethink.

Same question as above: is the goal of the SDK to use BuildStream
definitions, or is BuildStream just something which happens to be a
part of it?

I'd ideally suggest establishing the goals of the SDK in terms of what
it's meant to provide to external users. That's something which is
actually compelling and useful: fd.o doesn't usually get involved in
projects whose sole goal is to _use_ a new build system.

For the record, I would very much like fd.o to migrate to GitLab.

What kind of hardware? Is that something you'd expect from fd.o, or
would you reuse, e.g. flathub and GNOME Continuous? Do you need
hosting, or build machines, or test runners, or ... ?

Is this just for the SDK - which I understand at this point to be a
bunch of build recipes and a conversion script from JSON/Yocto to
YAML/BuildStream - or are you talking about BuildStream itself?

fd.o already has a Code of Conduct here, which we expect all new
projects to abide by:
https://www.freedesktop.org/wiki/CodeOfConduct/

If you have any specific input or suggestions, these would be welcome.
