Permission denied (publickey,keyboard-interactive).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

(This is without using an ssh key added to Phab – after all, I need a
build service to poll that, and don’t want to hand out keys to that.)

I’ll wait for the CDN to get working.

The build script needs to know that there are two repositories to poll from

Gipeda needs to produce a section, like the one for branches, for DRs,
which  have slightly different semantics (in particular, they have an
explicit base commit that comparisons should be made against, which is
not the case for git branches).

Hmm. Links to git diffs would also have to go to a different place.
Annoying complexity there. Maybe a separate gipeda instance is simpler
(but would get in the way of comparing commits on Phab with commits on
the main repo, and duplicate building work).

I’ll have to think more about how this can be done in a viable way.
