	System      : OpenBSD 2.8
	Architecture: OpenBSD.i386
	Machine     : i386
>Description:
        At the beginning of the install procedure, the user is asked
        whether the entire disk will be OpenBSD. If "yes" is entered, a new
        MBR partition is immediately saved to disk without user confirmation,
        as is customary.
>How-To-Repeat:
	
>Fix:
        Give fdisk a command option (used by the install program) to generate
        a new partition in memory, and do not save the new partition to disk
        until the "write" command is entered.
