youll do just as fine to hit 'A-S-Q" during the partitioning portion, and
taking the defaults. FreeBSD installer will take the best options, and put
all the remaining space as /usr.
i just put my jails under /usr/jails.
keep the host as simple as possible, as building multiple jails will just
multiply your complexity quickly enough.
i would also agree with Frederico... do a RAID1 with your (2) 250GB drives.
