If you are rebooting your DOMUs all the time, presumably they are not in a
production environment, so you have the luxury of time. In that case why not
build your own tailored kernels, or even better, spend some time to optimize
the boot process so that it's quicker?

Sure, I got that. I understand that fewer+larger kernel images doesn't fit
with your meticulous set of requirements, that you don't see the efforts
being made to modularize the kernel, and that you don't see the possiblities
that a modest level of standardization brings.

You probably shouldn't care about that, but I can't speak for you. ;-)
