I welcome suggestions. Your first suggestion would require entirely new
buildroot tags produced for each -override. New buildroots have a
significant cost in spin up, upwards to an hour or more for the first
repo generation. Do you really want to introduce an hour+ delay in your
build every time you need an override, not to mention the vastly
increased load on our backend filesystem?
The second suggestion would put significant blocks in our build windows,
since we get override requests on a daily basis. If only one could be
done at a time, and we had to wait until the build was finished before
moving on, we'd have a serious backlog and almost never have a window
for doing builds without any override tags in play.
We take a measured risk with our current system, because that's the best
balance we can strike right now.
