suggestion:
ISO kernel should be SMP, definetely for x86-64. It does not break
the uniprocessor systems and you gotta search hard for a x86-64 box
with a single core nowadays. At least there should be the option to
copy prepared SMP kernel to the installed system. Rationale is that
especially during sorcery rebuild, you don't want to use only 1/n of
your processing power.

For x86_64 systems, this should be useful... since most modern systems
are multi-core nowadays. On x86 this cannot be done due to some people
still running i586 or lower systems.


AFAIK, having SMP on the kernel only makes non-smp systems a bit (probably not noticeable, especially for the install phase) slower. The kernel simply will see the system as a SMP system with one CPU. It'll unload from ram any extra cpu handling stuff, thus freeing up the ram.

But it doesn't really hurt anything (much) leaving it non-smp anyway.

I'm indifferent.
