I assume you're only encouraging this because it's likely impossible.
Frankly, I find the FreeBSD installer somewhat confusing. About the
only thing that would maybe make the OpenBSD installer simpler for new
(or impatient) users would be a "default" disk layout with sane
partition sizes for /, /tmp, /var, /usr, etc. Of course I rarely
install OpenBSD on non-x86 boxes but I'm sure sane defaults for x86 are
quite different than mac68k or hppa.
(In my defense, i do have a Sparc Classic and several mac68ks here.
Great machines for SETI@home.)
