As I've said here several times before, the 2nd edition contains material
that was released under the conditions of its license, which included a
transfer of money.  The 3rd edition has a different, cost-free, open-source
license.  Some things, such as the sources for SGI and SUN machines,
were excluded from the 3rd edition because we didn't have permission
to release it under its license terms.

You need a 2nd edition license to get the SUN material, and once you've
got it you can't expect any work based on it to be included in updates to the
3rd edition because we don't have the rights to release it that way.

I'm not even sure how to get a 2nd edition license now.  There were a
limited number of CDs printed and they're sold out and the publisher
who was handling the payment doesn't offer it any more.
