BTW, for the adventorous, one can nowadays on newer distros also
have vmlinuz/initramfs live on LVM.  This can be tried out i.e. on
Fedora 19 or 20.
There are cases where it does not work reliably, so it did not make
it into Red Hat Enterprise Linux.

With that functionality one is no longer forced to have /boot on a
partition, the / volume can then be snapshot and directly contains
/boot.
