Hmmm, we've found it to be relatively easy. The biggest problems that we've seen are with /dev (which is hard to update with the current rc.diskless2), the need to customize /var directories (a simple mtree helped to fix this and the need to have a few files in /etc read/write (/etc/resolv.conf and /etc/ttys are needed for our product).

I know that Timing Solutions would be very interested in this. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
