>Release:        FreeBSD 2.0-BUILT-19950603 i386
>Environment:

	FreeBSD 2.0.5 installed on SCSI drive. The system has 2 SCSI drives and
    1 IDE drive.

>Description:

	disklabel -B won't install boot blocks if it finds trouble in the
	disk label. Not a bad thing, except that the label installed on the
	drive has a superblock size of 0. The disk label was installed with
	sysinstall.

>How-To-Repeat:

	Install FreeBSD onto a SCSI drive on a system with an IDE drive.
	Try updating your bootblocks with disklabel -B

>Fix:
	
	One way of getting around the problem is to comment out the check of
	the disk label when only writing boot blocks. However, this probably
	isn't the safest thing to do. It looks like either sysinstall needs
	to correct the disk label it writes, or disklabel -B shouldn't be
	so anal about how it checks the disk label.
