Some combination of the above, primarily the first two. Right now the
system is functional but its code is not exactly up to our normal FOSS
configurability / maintainability standards. I could clean it up, make
it easy to configure for other test systems, and generate documentation,
but that would require time + proper motivation (e.g. put the work under
contract with my company).
I also want to let the test stand run for a month or two to make sure
some unforeseen corner case doesn't take it out--this delay can be
decreased significantly by throwing random Gerrit changesets at it
(including failures to build, NVRAM layout changes, etc.) until I'm
confident it won't break under normal use.
One of my main concerns is that unless the test rig is 1.) inexpensive
and 2.) almost fully plug + play people won't bother to set it up / make
it available for use.
Right now the test stand requires an external NFS server and SMTP
access, along with a 24/7 Internet connection. It doesn't use Java at
all; only needing around 500 lines of Python. The test coreboot image
is built on the target itself, which is only powered on for compilation
and test, thus saving energy.

This is one of my main concerns ATM. If this is something the coreboot
community wants badly enough I can provide a professional open-source
solution. If not, I'll continue to run the test stand here as both a
courtesy to the community and a double-check on bootability for the
systems in use here.
