In order to automate the complete bootstrap build process we need a mechanism to control the second phase which builds the final packages on the booted bootstrap Haiku. To avoid additional dependencies (buildbot slave, ssh, rsh,...) we'd have to cross-build, there's now a pair of simple python scripts that allows executing commands on a remote machine. The server script (bootstrap_daemon.py) is added to the bootstrap image and started automatically during the boot.
