Way back in the mists of time (uh, something like that 2004-05) I had some 
discussions with some of the S390 people about using kboot for more flexible 
boot, since it tallied with their interests.  Although at that point I had the 
impression that zipl was restricted to only one boot option anyhow, so if it 
can now choose from a list then maybe they just enhanced what they had.

Anthony, you might remember these discussions?  I don't know if they went 
anywhere with it.
