ROM image size

I’ve built a RasPi ROM image from very recent sources, and I can see that the image is nearly twice the size of a comparable nightly build from the ROOL site. Compression must be involved, but I can’t see anything in the Builder app that mentions it.

It’s not a big problem – it can possibly limit the number of images that can be stored in a Loader partition and swapped between, that’s all – but I’d like to know if there’s a switch or setting somewhere that I’ve missed.

Compression is handled by the scripts which package the ROM up into the zip file (Utilities.Autobuild.ABRelease). The autobuilder runs these as a separate step once Builder has finished.
