37 .Nd update disk label from MBR label(s)
47 disk label from the Master Boot Record (MBR) label(s) found
48 on disks that were previously used on DOS/Windows systems (or
49 other MBR using systems).
52 scans the MBR contained in the very first block of the disk (or the
53 block specified through the
55 flag), then walks through every extended partition found and generates
56 additional partition entries for the disk from the MBRs found in
57 those extended partitions.
59 Each MBR partition which does not have an equivalent partition in the
60 disk label (equivalent in having the same size and offset) is added to
61 the first free partition slot in the disk label.
62 A free partition slot is defined as one with an
70 If there are not enough free slots in the disk label, a warning
73 The raw partition (typically partition
77 on i386 and some other platforms) is left alone during this process.
79 By default, the proposed changed disk label will be displayed and no
80 disk label update will occur.

86 Force an update, even if there has been no change.
88 Performs operations in a quiet fashion.
90 Update the in-core label if it has been changed.
94 also update the on-disk label.
96 Specifies the logical sector number that has to be read from the disk
97 in order to find the MBR.
98 Useful if the disk has remapping drivers on it and the MBR is located
99 in a non-standard place.
