(that is, call the build hook with a certain interval until it
accepts the build).
* build-remote.pl was totally broken: for all system types other than
the local system type, it would send all builds to the *first*
machine of the appropriate type.
scan for runtime dependencies (i.e. the local machine shouldn't do a
scan that the remote machine has already done). Also pipe directly
into `nix-store --import': don't use a temporary file.
(e.g. an SSH connection problem) and permanent failures (i.e. the
builder failed). This matters to Hydra (it wants to know whether it
makes sense to retry a build).
makes more sense for the build farm, otherwise every nix-store
invocation will lead to at least one local build. Will come up with
a better solution later...
necessary that at least one build hook doesn't return "postpone",
otherwise nix-store will barf ("waiting for a build slot, yet there
are no running children"). So inform the build hook when this is
the case, so that it can start a build even when that would exceed
the maximum load on a machine.
list like
root@example.org x86_64-linux /root/.ssh/id_buildfarm 1
root@example.org i686-darwin /root/.ssh/id_buildfarm 1
This is possible when the Nix installation on example.org itself has
remote builds enabled.
