The best strategy is to *not* introduce build failures :-)

Well supporting alternate repo/branch is about testing different
Buildroot versions, not about testing in different environments.

I think we don't need anything special: an autobuild instance running
in a sandbox can be considered as just another autobuild instance. Just
like some autobuild instance run with Debian, others with Fedora, with
varying versions of distributions and installed packages.

So you could have an autobuilder instance running inside a sandboxed
environment, and report results to autobuild.buildroot.org with a
clearly identified "submitter" content that allows to know it's a
sandboxed instance.

To run this, I guess you have two options:

 - Run the entire autobuild-run stuff in a sandbox.

 - Modify autobuild-run so that it can optionally run just the build
   inside a sandbox.

Best regards,

Thomas
