Actually I did read somewhere that it is possible. Technically you only need
to use the SD card to boot to init, so modify your /etc/fstab to change the
location of your root partition to the device of the USB drive.
(Theoretically, I haven't booted my Pi's in quite some time.. rapidly losing
interest in running a BBS) ..
The root filing system is determined by what is in cmdline.txt of the sdcard (or the FAT like filing system on the first device it finds). What is in /etc/fstab wont change the root filing system in use.
I am not so sure about that
At some stage during boot, fstab is used to (re) mount all partitions
I *think* that what happened in my case was that the root system was on SSD., but the linux image itself was from the SD card
