I always test new versions of FreeBSD on USB keys, right now while
typing I run a 11-CURRENT with KDE ... and mutt as MUA booted from an USB
key, while the disk in the laptop has still an older FreeBSD.

The procedure to creat a boot-able USB key is simple:

- make a file system on it 
- mount it to /mnt
- do 'make installkernel' and 'make installworld' with DESTDIR=/mnt
- enrich the file system in /mnt with some stuff (for example install
  packages into it with 'chroot /mnt pkg install ...')
- unmount and reboot

even better, if you do not use an USB key directly, but do all the above
to a mdconfig file system (a file system in a normal plain file) and
copy later the result with dd(1) to the real USB key;

let me know if you need a detailed procedure of it.

HIH
