Public bug reported:
If you remove a kernel-image package, and its kernel-module packages,
the system will be doing very costly and slow runs of update-initramfs.
The system should be smarter, and detect that the kernel-image is being removed
as well.
If so, the very laborious step of update-initramfs can be avoided.
For instance, see this output:

[EMAIL PROTECTED]:/boot/grub# lsb_release -sd
Ubuntu 8.04.1
This bug makes removing kernel images a very slow process.
I had to wait an unacceptably long time for the above command to finish.
** Affects: linux-restricted-modules (Ubuntu)
Importance: Undecided
Status: New

update-initramfs is being run needlessly for a kernel that is being removed.
