FreeBSD can mount and use filesystems created on partitions inside
'extended partition' type slices (cue standard exposition of the
difference between partitions and slices in FreeBSD-speak.) True.
However, I believe that you may well have difficulty *booting* FreeBSD
unless the kernel (ie. /boot) can be read from a primary partition.
Also, I don't think sysinstall(8) groks extended partitions very well,
so you will probably have some fun doing the actual installation.
Certainly not impossible, but not something you should contemplate if
you still consider yourself just a beginner.
Of course, this discussion only applies to DOS MBR style partitioning,
which is fairly rapidly going the way of the Dodo (at least in the
FreeBSD world.) Unless you need the backwards compatibility, GPT looks
like a much more attractive proposition for a new machine nowadays.
Cheers,
Matthew
