>Description:
One can only use an ISO image to install from (boot-only image). It would be
great if FreeBSD would have a USB Stick image as well.
Dario Freni has written a script that lets you convert an ISO image to a
bootable disk image with a UFS partition.
It would be great if the release process would spit out such an image as well.
It's so much easier to take a stick with you, stick it in a machine and then
suck FreeBSD off the Internet onto that machine.

I cannot find the link no more, so I've included the script written by him

# 1 if you want comconsole and 2 if you want comconsole and vidconsole
