Configuring the host-side environment (which host serial port gets
used to talk to the target board, what local machines can be used for
network operations, how to access the webcam so that the test harness
can check that LEDs flash when they are supposed to, ...) should be
separate from configuring the target-side. At the point that a test
case is run there should be a suitable transfer of information. A
change in the host-side setup should not require any target-side
configury or rebuilding.

For example, if a technical support customer were to send in a
configuration savefile that is causing problems then we should be able
to rebuild directly from that savefile, with no need to edit the
target-side configuration to match our host-side setup.

This is not possible right now because we do not do a very good job of
host-side setup configury yet. Until then ad hoc approaches such as
server address config options may have to be used, but long term there
are better solutions.
