Raising a scenario occupies the machine and the person who started it, and
running in the background against a working copy is worse than waiting: a run
reads that copy as it goes, so editing while it runs yields a result describing a
state that never existed.
Proposed rather than accepted. The load-bearing part is the restriction — a
request names a bed and a commit and nothing else — because a request that could
say what to install and where would make the lab a second way of installing a
mesh, which is the arrangement that just cost a year of late-found faults.
