I should have removed those long time ago, as FreeBSD has been EOL for
ages.

Is this purely a name change, or there's some kind of functional
change?

I'm mostly worried whether this could lead to regressions getting in
as osstest would detect those jobs as new instead of inheriting from
the previous jobs.  Also the "History for test ..." won't link to jobs
prior to the rename?

I guess I'm confused about what causes the qemuu to be dropped from
the job names above.

Thanks, Roger.
