It has two kernel versions - one is WORKING and the other is TEST - the one I am presently working on. Is it possible that the bootloader tries to first load TEST but in case TEST panics then it loads the WORKING version of kernel without user intervention ? My initial guess would be to use loader scripts. Any suggestions? Thanks Rashim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
