Fbsd1 writes: > just dd the image to what ever drive you want That is the goal. The challenge is to launch a script that detects when the boot device has been unmounted as dd will not work on an active file system. Memory disk images apparently survive until reboot so there is a possibility that one can get in the write between the umount of everything and complete shutdown. I am truly impressed with how robust FreeBSD is as it probably should be very hard to log in to a working system and remotely rebuild it. I did read one of many introductory articles about mfsbsd that tells you to just use scp to get the image over to the target system and then, as root, use dd to apply it to the boot device. That is not possible unless one first boots from some other medium. Martin McCormick
