    If you use the standard FreeBSD MBR bootstrap program, boot0, and you
    configure it with the "noupdate" option (an uncommon configuration) and
    you have two bootable FreeBSD slices on that disk, then you can boot only
    one of them without editing the MBR slice table. (Whichever one is the
    "active" slice or the first one if neither is active.) This is due to a
    limitation in the bootstrap design. (There is apparently no convention
    by which the boot0 program can pass the booted slice number to the boot1
    program.)
