The boot slice contains the bootstrap code. AFAIK, the slice is required on S-x86, because the bootstrap code has grown too big and doesn't fit into the spare sectors at the start of a regular UFS root filesystem any more. Instead, the tiny extra slice tagged "boot" is used (that must not overlap any other filesystem / swap slice). > The other is usually tagged alternates and uses 1 or > 2 cylinders after the boot slice. The "format" -> "analyse" command uses it when trying to repair bad sectors, and the disk hardware doesn't remap bad sectors transparently. Shouldn't be used any more with modern disk hardware.
