That would be cool to have all that stuff tossed into a .builder file, but I thnk Mark is referring to the builder utility that simply formats the drives for the empeg (and does not install the empeg kernal or software.)

the builder upgrade file is the same format as any of the regular ones, you see it go thru the motions (erasing kernel, flashing kernel, pumping partition). anyway, the builder seems to contain programs and scripts that prepare the partitions, which arent avaliable in the other image files.

come to think of it... easiest way to get over 128GB with the current builder image is to install hijack, then use the ethernet upgrader. it will leave the hijack kernel in tact, and assuming tat >128GB is compiled by default, this should work fine.
