First of all, that command would be incorrect, because it would create the
initrd image in the root directory as opposed to the /boot directory,
which is on a different partition. Your grub.conf file says that you
have /dev/hda1 = /boot and /dev/hda9 = /. Creation of the initrd can
fail if /boot is out of space.

It should be reproducible, too, i.e.

 * install previous kernel (-28.7)
 * reboot to previous kernel
 * erase -30.7 kernel
 * apt-get -30.7 kernel

Is it?

I doubt that. There is no reason to assume that the kernel update from
28.7 to 30.7 has changed anything that would break initrd creation.
