I'm looking for a clever fool-proof way of deselecting the SMP kernel.  I've 
just installed SL 4.6 under Mac Parallels for a colleague.  It doesn't boot 
with the SMP kernel; only the UP kernel.  So, I selected the appropriate 
kernel with the 'default' setting in grub.conf.  The question is what 
happens when yum updates the kernel.  Obviously, it puts the new kernels (up 
and smp) at the top of the list.  Can I rely on the order of the kernels 
listed in grub.conf?  Does it alter the 'default=1' line?

One alternative is to remove all smp kernels, add a kernel-smp* to the 
yum.cron.excludes so it never updates the virtual SL machine with an SMP kernel.

I'd appreciate any advice you might have on this matter.

Thanks! Ken
