Nope. They belong to initramfs-tools. Th scripts provided by
kernel-package (which would have worked here, BTW) are:
/usr/share/kernel-package/examples/etc/kernel/postinst.d/initramfs
/usr/share/kernel-package/examples/etc/kernel/postrm.d/initramfs
So, if you use those scripts, things will work. If you want to
use the scripts provided by initramfs-tools, you have to wait until the
wishlist bug is fixed.

Actually, it does, but the script ignores the invocation.

Right, you are not running with the same number of arguments
that the postinst does, and thus the initramfs-tools scripts no longer
ignore you.

From:
/usr/share/doc/kernel-package/README.gz
Note that you will have to arrange for the actual
initrd creation to take place by installing a script like
/usr/share/kernel-package/examples/etc/kernel/post{inst,rm}.d/yaird
or, alternately,
/usr/share/kernel-package/examples/etc/kernel/post{inst,rm}.d/initramfs
into the corresponding directories /etc/kernel/post{inst,rm}.d,
since the kernel-postinst does not arrange for the initramfs
creator to be called. You can thus select your own;
initramfs-tools or yaird.
Let me repeat:
Since nothing is created automatically. you need to provide a hook
script for things to happen when you install the kernel image
package. The user provides such scripts. For example, to invoke
mkinitramfs, I did:
--8<---------------cut here---------------start------------->8---
cp /usr/share/kernel-package/examples/etc/kernel/postinst.d/yaird \
/etc/kernel/postinst.d/
cp /usr/share/kernel-package/examples/etc/kernel/postrm.d/yaird \
/etc/kernel/postrm.d/
--8<---------------cut here---------------end--------------->8---
Or, alternately, you could do:
--8<---------------cut here---------------start------------->8---
cp /usr/share/kernel-package/examples/etc/kernel/postinst.d/initramfs \
/etc/kernel/postinst.d/
cp /usr/share/kernel-package/examples/etc/kernel/postrm.d/initramfs \
/etc/kernel/postrm.d/
--8<---------------cut here---------------end--------------->8---
These scripts above to nothing unless the corresponding
packages are installed (initramfs-tools or yaird), so you could
potentially cp both over -- as long as you never install both yaird
and initramfs-tools at the same time.
To run grub, I have in /etc/kernel-img.conf:
--8<---------------cut here---------------start------------->8---
postinst_hook = update-grub
postrm_hook = update-grub
--8<---------------cut here---------------end--------------->8---
You can look at other example in the examples directory:
/usr/share/kernel-package/examples/ to see if there are other example
script you want to cp into /etc/kernel -- and you can create your own
scripts.
For example, if you use linux-headers-* packages to compile third
party modules so that you do not have to keep the sources directory
around, you might be interested in:
--8<---------------cut here---------------start------------->8---
/etc/kernel/header_postinst.d/link
/etc/kernel/header_postrm.d/link
/etc/kernel/header_prerm.d/link
/etc/kernel/postinst.d/force-build-link
/etc/kernel/postrm.d/force-build-link
--8<---------------cut here---------------end--------------->8---
