This is one of the things that makes securelevels less than useful.
You'll find that you can't write to /dev/sd0a if it is mounted, but
you *can* access the 'c' partition.  Initially, installboot operated
on the 'a' partition but it now opens 'c' and seeks to the beginning
of 'a'.  The man page for installboot is confusing, I'll update it.
