The size of the ufs image is calculated from the iso one. The usage for the script is quite simple: =2E/fbsd-install-iso2img.sh iso-path img-path Once you're done, you can dd the img directly to an USB pen. If you also want to make a serial-console install image just set the serial variable on top of the script to 1. This script is derived from another similar one that I made for the pfSense project. It was requested for those kind of systems which have an usb port booting-capable and a serial console. I hope you'll find it useful.
