In any case, the reason why I bring this up is that it would be really
nice if there was a way with a single laptop drive to be able to do
snapshots and background fsck's without having to use initrd's with

This is a major part of why I've been trying to push integrated klibc to 
have all that stuff as a unified "kernel" deliverable.  Unfortunately, 
as you know, Linus apparently rejected the concept "at least for now" at 
LKS last year.

With klibc this stuff could still be in one single wrapper without funny 
dependencies, but wouldn't have to be ported to kernel space.
