Clarification question: is it only the size of the root file system that
is limited, or is it also the location of the root file system on the
disk?  I.e., is a 256MB file root file system located 1.7TB into the array
also going to not work?  I was going to commit this to the partitioning
documentation in sysinstall:

  WARNING: FreeBSD on i386 is currently unable to boot from file
  systems larger than 1.5TB, so the root file system must exist
  entirely below the 1.5TB mark.

But it ocurred to me that I was being unclear as to whether it was the
size or the location and size that mattered.  Could you make the language
above right? :-)
