if we use the numbers to infer if its stable vs. devel, please make a big buffer (e.g. make all stable silos start with 5XX) so we can grow silos without having to make the scheme more complicated. I am in favour of not using the numbers for stable vs. devel. > >> >> * How will we handle this in the spreadsheet?

I think all projects that have to diverge will have -rtm branch. All projects that just land isolated fixes after we do the forking could possible continue to deliver into trunk only and land in ubuntu-rtm and ubuntu at the same time. > >> >> >> * Presumably the backend and the dashboard would both need to be >> extended.
