Thanks for the advice.

This may seem a novice question, but can you build a 2.6 kernel and  
use it to boot a system built against 2.4?  That is, to divide the  
move into two testable components, kernel and everything else,

1) Build a full new system on the redundant drive with a 2.6 kernel
2) Copy *just* the kernel over and test it (with a menu in grub as you  
suggest in case it barfs)
3) If the kernel works, then move the rest over

Or does the kernel change enough between major iterations that you'd  
have to, say, rebuild glibc or somesuch?

Cheers,
