That came from the old Unix design - but BSD changed a lot of
things - for the better IMO - when they came up with BSD - upon
which FreeBSD is based.
The original UNIX systems needed a LOT of things that are in /usr
when it started up.
In the BSD systems the /usr is separate and everything you need to
boot the system up and get running [ up to a point ] is in /
This makes it quite clean. And in BSD the /usr/local is where all
user add-ons are kept to keep them from poluting the OS >AND< it
also means you can totally reinstall the os on / without affecting
any of your installed applications.
On old Unix systems when drives were smaller and /usr was needed
for boot, but was too small, one trick was to copy the files
in /usr to another filesystem, and after the system booted
mount that other filesystem on top of the original /usr
Gad - I hated those kludges.
But to see how FreeBSD is laid out try 'man hier' and you'll see
the layout and recommend file system hierarchy.
Once you get used to it you'll wonder why you ever managed to live
with the SysV based systems :-)

You can find all about your hardward by looking at
/var/run/dmesg.boot. That file has everything that is found by the
system at bootup.
