     apmlabel - update disk label from Apple Partition Map

     apmlabel [-fqrw] device

     apmlabel is used to update a NetBSD disk label from the Apple Partition
     Map found on disks that were previously used on Mac OS systems (or other
     APM using systems).

     apmlabel scans the APM contained in the first blocks of the disk and
     generates additional partition entries for the disk from the entries
     found.  Driver and patches partitions are ignored.

     Each APM entry which does not have an equivalent partition in the disk
     label (equivalent in having the same size and offset) is added to the
     first free partition slot in the disk label.  A free partition slot is
     defined as one with an fstype of `unused' and a size of zero (`0').  If
     there are not enough free slots in the disk label, a warning will be

     The raw partition (typically partition c, but d on i386 and some other
     platforms) is left alone during this process.

     By default, the proposed changed disk label will be displayed and no disk
     label update will occur.

     Available options:

     -f  Force an update, even if there has been no change.

     -q  Performs operations in a quiet fashion.

     -r  In conjunction with -w, also update the on-disk label.

     -w  Update the in-core label if it has been changed.
