It doesn't much matter to me personally since my distro ;) seems pretty 
well committed to using the blkid & libuuid now in util-linux-ng.

I guess I'm not thinking too much about a world where people are pulling 
down tarballs & doing make install; I'm sure that still goes on but 
those folks are smart enough to handle things moving around, or should be.

*shrug*

As long as we can teach the e2fsprogs build to optionally pull libblkid 
& libuuid headers from the system rather than the e2fsprogs tree, it'll 
give the flexibility we need.
