Dedicated or shared disk?

The installation procedure bypasses /etc/disktab and does the entire
job "manually". The magic for this is in /usr/src/release/libdisk.
You are free to use disktab(5) and disklabel(8) yourself. You shall
provide a `c' partition covering the entire FreeBSD slice, which
*must* start at offset 0. (It's relative to the start of the slice).

fdisk(8), though it's user interface sort-of sucks. The man page of
fdisk in 2.0.5 does not reflect the reality. :-(
For a dedicated disk, you can also bypass the fdisk step and work with
no fdisk partition (aka. slice) table at all. In this case, use a
non-sliced device name (e.g. `sd1' as opposed to `sd1s1'), and your
`c' partition covers the entire *disk* then. This means the bootstrap
goes to absolute block 0, not allowing to share the disk with anything
else.
