Not a huge deal in it that gives (me) clues:

</I>>><i> I was under the impression the initrd would be regenerated at the end?

</I>
What if the initrd is present? e.g. it was created when the kernel was
installed. Would it still be REgenerated at this stage? (I always
presumed it would be or that it was not generated at the install time).
Looking at the script /sbin/installkernel I see:
[ -z "$DURING_INSTALL" ] || exit 0
So it shouldn't do anything when run as part of the kernel post
install... So perhaps some other package triggers an initrd generation?
Looking at things happening live... I see that the symlink
initrd-desktop.img is created, but it points nowhere. I wonder could one
of the bootsplash scripts do something like resolve the symlink name and
then recreate the initrd automatically because the file does not exist?
