So far I have a `master' OS which permanently occupies a slice and which remaps slice entries of `slave' OS'. But when I have slave1 OS running and want to reboot to slave2 OS I first reboot the master OS and do the remapping before I reboot slave2 OS. What happens with FreeBSD if it's slice entry is removed in the MBR before it is shutdown? Can it safely shutdown and unmount like this? The slice entries in the MBR are probably needed by the boot selector, by fdisk, by disklabel and when mounting foreign filesystems and maybe by fsck. Is a valid slice entry required by FreeBSD before/during shutdown? -Hanspeter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
