If anyone is interested the attached script will format a USB flash
drive, and create the necessary magic to boot off.
I think this would be a useful addition to the 'make release' stuff -
you can run the script with a install CD directory made by make release
and it will give you a USB stick you can install from (you also need to
copy the dist files :)
I think it would be good to include the image on prebuilt ISOs so you
can then get users to use something like unetbootin in Windows to copy
the ISO bits onto a USB key. It requires an extra 15Mb of space, not
sure if that's a big deal on a CD (should definitely not be on a DVD)
The script needs makefs which is in head but not 7.x (easy to build
there though). It also needs the sysutils/syslinux port installed.
