Thank you for the background. Omitting the swap area saves less than 10% of the time to dd the image (128 MB out of 1536 MB); if there are no other reasons to maintain two separate images, I don't think it's worth it just for that. > Note one more TODO item is to use makefs(8) -O (offset) option like > src/distrib/utils/embedded/mkimage, to avoid concat MBR + ffs image files. That would be good, but I think it's orthogonal to the issue at hand. Also, it looks like it would require adding an offset option to installboot as well. -- Andreas Gustafsson, g...@gson.org
