Precisely.  Now I have to use a semi-magic invocation of dd(1) to do
what I want, because there's a fairly arbitrary restriction in
fdisk(8).  That's lame.  It's also distinctly *un*like what the DOS
FDISK does -- and it's actually pretty broken, in that it assumes that
the signature being present means there's valid boot code.
