I was thinking on this. So... what if there is a fourth dimension for 
choosing if the job description goes first or second in the mkisofs command?

E.g.:
xorriso bunch-of-options-1 -eltorito-alt-boot bunch-of-options-2
versus
xorriso bunch-of-options-2 -eltorito-alt-boot bunch-of-options-1

So you don't like the primary or secondary terms.

How does xorriso name them?

Given that man xorrisofs talks about:

-eltorito-alt-boot

maybe we can just name them as:

"Main bootloader"
and
"Alternate bootloader".

Or maybe even better:

"Main eltorito entry"
and
"Alternate eltorito entry"
?

So that we can force a given bootloader to be used only as a "Main 
eltorito entry" ?


What do you think about this idea?
