link to /sbin/update-grub missing, problem with update of linux-restricted-modules-2.6.28-13-generic

[Wolfgang]

Binary package hint: grub2

Description: Ubuntu 9.04
Release: 9.04

after upgrade to grub2 the (normal security) update of the kernel-packages in jaunty failed today with the following error message:

...
update-initramfs: Generating /boot/initrd.img-2.6.28-13-generic
The provided postinst hook script [/sbin/update-grub] could not be run.
...

It seems grub2 does not provide a symbolic link /sbin/update-grub, however there seems to be a link in /usr/sbin/update-grub. Info: As recommended, I purged the package "grub", after successful grub2 installation!

Due to backward compatibility reasons, grub2 should also provide a symbolic link /sbin/update-grub

Workaround:

set symbolic link:
# ln -s /usr/sbin/update-grub /sbin/update-grub
then run upgrade again:
# aptitude -y dist-upgrade

grub-legacy provides since version 0.97-14 a wrapper in /sbin/update-grub which tells you that /sbin/update-grub is deprecated and /usr/sbin/update-grub should be used.
But it doestn't mention unfortunately that you need to change /etc/kernel-img.conf
In Debian's grub2 1.96+20090611-1 we just run sed over it and change it in the postinst.
