As I suspected:

>1. Is JumpStart a throw-away program designed for one-time use?

Yes.

>2. Is JumpStart what's on the disk (sd0a)?

Yes.

>3. Is JumpStart part of the ROM monitor?

No. But it didn't hurt (too much) to ask.

>4. Should I care?

Only when it involves Maslow's Hierarchy of Needs: food, shelter, sex, .... :-)

>5. Anyone want to take late bets on the Super Bowl? :-)

Damn. I forgot to say which year. :-) :-)

Other tidbits:

        See /etc/.install.d/re-preinstall-svr4, TFAnswerBook and friends.

        You gotta boot MUNIX (memory unix) to create a missing "b"
        partition before you can install the mini root into it.

        JumpStart is good for monoclonal antimegamonolithic kernels
        (sometimes).

        Use the CD when you're ready for some culture shock (Solaris 2.x).
        I personally tend to be cautious though when I see

              /devices/pseudo/sad:admin
              /devices/pseudo/sad:user

        in the distribution.

Mail me if you want the actual replies.
