Documentation: from fdisk man page; Is this in the install manual?
This is important information and I wonder if it is mentioned in the
installation manual (for Intel arch)? If not, it should be, IMO.
If possible, fdisk will obtain the disk geometry automati-
cally. This is not necessarily the physical disk geometry
(indeed, modern disks do not really have anything like a
physical geometry, certainly not something that can be
described in simplistic Cylinders/Heads/Sectors form), but
is the disk geometry that MS-DOS uses for the partition
Usually all goes well by default, and there are no prob-
lems if Linux is the only system on the disk. However, if
the disk has to be shared with other operating systems, it
is often a good idea to let an fdisk from another operat-
ing system make at least one partition. When Linux boots
it looks at the partition table, and tries to deduce what
(fake) geometry is required for good cooperation with
-- fdisk man page.
