Looks like grubby is called from /sbin/new-kernel-pkg - when a new
kernel is installed.  It has:

*************
    rootdevice=$(awk '{ if ($1 !~ /^[ \t]*#/ && $2 == "/") { print $1; }}' /etc/fstab)

        /sbin/grubby --add-kernel=$bootPrefix/$kernelName-$version $INITRD    \
                     --copy-default $makedefault --title "$title"           \
                     --args="root=$rootdevice $kernargs"            \
                     --remove-kernel="TITLE=$title"

*************

So it grabs the 'root' partition from /etc/fstab - and uses it. So the
correct root-label is always used when kernel gets updated. (i.e no
problem with this scheme :) )
