We're only doing this once a month, we should just produce images for everything rather than trying to second guess which we can get away with not generating.
While that's a nice sentiment, we can't ignore the disk space usage that this implies.
If we take as an example 6 supported boards, and 6 images (3x2G, 1x1G, 1x.5G, 1x.1G), that's ~48G per month, so in one year ~0.5T of images. I haven't done the maths to factor in the bandwidth here.
I don't quite understand your maths there; if you look at the Ubuntu ARM images they are 540MB for netbook and 200MB for headless (compressed). So at 6 boards to support that's ~4.2GB/month or ~50GB/year which is a lot less scary.
We decided that we would pregenerate one image size with some free space that can be directly written to an SD card.
Thanks,
