Multiple distros, location of the /boot partition and kernel updates

[Jongi]

I currently have FC5 as my main OS and have also installed Kubuntu and SUSE10.1. Grub uses the FC5 /boot and menu.lst.

1 - I assume that if I upgrade the Kubuntu kernel I will have to manually update the menu.lst under the FC5 install to reflect the new Ubuntu kernel?

2 - How do I create a new /boot partition and yet not mess up the booting of FC5 and Ubuntu? By create I don't mean the actual creation of a partition, but moving /boot from being on the / partition to its own /boot partition. Not sure that makes sense.

3 - Will creating a separate /boot partition actually solve the problem of having to manually update menu.lst? That is, will menu.lst now reside on the newly created /boot partition and as such available to all the distros?
