Like jeremy said the USB stack ain't overly sexy. Altho as far as i've used it umass hasn't caused too much problems. If you are building kiosks or similiar systems that are mostly used to launch programs and not write too much to the disk then installing on a 'el cheapo usb thingy might be just the thing. I did something similar a little while back (linux tho) and it's quite simple/cheap for something like that. 2 things. - mount with noatime (wearing the memory just because accessing files is quite stupid) - make sure your system has enough memory to avoid swapping, while you can certainly put a swap on flash i wouldn't recommend relying on it as the errors that finally crops up could be subtle and catastrophic or just errors. (how does freebsd handle a swap disk going bad?) / Jonas
