I highly recommend using genext2fs instead of a loopback mount;
that way you don't need to be root at all when making the image.
Stock genext2fs doesn't handle ramdisks bigger than 8MB, but
there are patches that fix this, and I've been using them happily
for about nine months. (Maybe they're in the mainline now; not sure.)
