You might try just extracting the tarball, editing the shadow file removing
the root password altogether (::), then, re-tar the extracted archived then
re-flashing with the updated tarball. Then hit 'enter' for the the root
password, and then set it to whatever you want after login as root. This is
of course untested and possibly bad advice. And of course depends on the
last bullet item you listed below.
