[Buildbot-devel] building from a tarball?

[dustin at zmanda.com]

I'm interested in doing roughly this for my build process:
 1. build a tarball on one of a small group of properly configured boxes
 2. ship that tarball to other slaves
 3. build from the tarball

1. Is fairly straightforward (make dist)

2. Can be done with FileUpload and FileDownload

3. Is harder: a ShellCommand of "tar -zxf blah.tar.gz" fails because the
'build' directory doesn't exist yet.  My solution was to make a custom
subclass of Source, and override its startVC function.  Is there a
better way?
