machine agent cannot start

Cannot reproduce; error looks very much reminiscent of a failure to upload tools. Please add further details.

Could this be caused by cmd/builddb/main.go failing to compile after rev 1089 - "state" imported and not used.
I'm proposing a trivial fix for that now, so after landing it, could you try again to see the bug is resolved please?

I have worked my way back to rev 1077 using juju bootstrap
--upload-tools (I always do upload tools). Unless somehow --upload-tools
has been broken recently, I blame rev 1078.

With a fudged version string to ensure I could not be picking up stale
tools.

Discussed online: the problem is that tool search falls back to another bucket with incompatible tools for machines with series not matching that from --upload-tools.

I will resolve this by:

 1) Eliminating the cross-bucket fallback: if any tools exist in the private bucket, the public bucket will be ignored. In the given situation, this will cause the deployment to fail at provisioning time due to lack of tools, which I think qualifies as an improvement.

 2) Adding a --fake-series option, to go with --upload-tools on bootstrap and upgrade-juju, that uploads an additional copy of the built tools for each given fake series. This allows a developer running (say) quantal to upload tools for (say) precise, and thereby test cross-series environments.

(2) has been merged, hopefully unblocking a few people. Cross-bucket fallback is still to be addressed.
