I think the quick answer is that the kernel on the install CD uses a built in image of a memory file system to mount as root. So, the default root device is a memory file system that can be guaranteed not to change (and permits you to remove the CD ROM once booting is over I think). This is probably the reason why FreeBSD needs more memory to install as conmpared to running normally (16MB for install vs. 6MB normally?). I think it is MDROOT/MFS or something similar in the kernel configuartion file. There are also man pages, but I forget the specific terms (mdroot() maybe? definately mfs(4)). ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
