Sorry for my inaccuracy: Of course the slicing part as well
as the BSD partitions are _both_ replaced by GPT partition

That article should be on the top of each list regarding
disk partitioning on FreeBSD, maybe something comparable
could be added to the Handbook?

As far as I know: no. You have to use the common CLI tools
if you want to install FreeBSD 8 on a GPT system (but it's
easily possible).

With the precaution of _not_ to vary existing partitions.
However, I don't know how the installer will handle the
non-MBR partitions (probably comparable to dedicated
partitions?), I've never tried that. (Even for dedicated
layout, I personally tend to use CLI only, without using
sysinstall or sade).
