I read the other replies but want to add this. I use grub for my boot loader. I use dracut to build the init thingy. It's really easy and I only had a bad init thingy once very early on, could have been my fault and most likely was. Since then, updating a kernel takes a lot longer than building the init thingy and updating grub. To be honest, if the linux link is pointing to the right kernel, one could likely script the dracut and grub update part. My point is, if you want to be sure you can boot without resorting to some rescue options, I'm sure any of us would help walk you through this. I actually have notes and I think it was Neil that shared his command and it is just plain easy. So far, Neil's command has not failed me once. I do mine by hand. I name my own kernels and the init thingy as well. Others have what is most likely a even easier and less time consuming method. You may can do it the way you are wanting to but for how long is the question. Odds are high that at some point, you will have a system that won't boot because something that's needed isn't there. I think Rich points that out pretty good. Just something to think on from a guy that really hates the init thingy. ;-) Dale :-) :-)
