I'm confused now. Is it autobuilder + new stuff in python and/or ptest
or something completely different? Are there already some examples in
git I could have a look at?

I use kernel over tftp and rootfs over nfs. The trivial example of a
boot loader upgrade is when you have a running (Linux) system just scp
it over. It's getting non trivial in case you manage to screw up the
boot loader. For the generic case maybe some update strategy with a
fallback solution to a known good boot loader might be needed.

kernel over tftp and rootfs over nfs should work with all boards.

Mutual exclusive access to the (serial) console can be handled by
conserver. Mutual exclusive via ssh gets more tricky.

I don't think it makes much sense to access the same board from multiple
autobuilders. This is most likely an error case which you would like to
catch.

OK understood. Please keep me updated.
