Fantastic! So when grub2's idea of device naming doesn't match what
the kernel ends up with, it will cause all kinds of odd failures.
This really needs to be done by Linux. As far as doing this stuff in
the kernel, one of the major motivations for klibc was to be able to do
this kind of stuff without having to have people write kernel code, but
klibc integrated into the kernel build didn't get enough support to
actually make it in -- it still exists and is maintained as a standalone
system, and it's possible to write a very small initramfs with it.
