annoying prompt from legacy-grub-ec2 on kernel installation

Marking this 'High' as initial 'apt-get update' (possibly from cloud-init) could hit this and go the wrong way.

on launch of a fresh instance, i ran 'sudo update-grub-legacy-ec2' and then installed the kernel, and saw no prompts.

I must need something done in the image post-processing, and likely its a result of me adding 'console=hvc0' under bug 606373.

I believe this will be fixed in the next builds. Anything 20100918 or greater.
To test, just launch instance, ssh in, wget kernel other than the one you have (or, identical to the one you have, but this bug was only found if it was different), and dpkg -i <kernel>.deb

Just verified on 20100920 image by installing a different versioned kernel with dpkg.

I used:
wget http://kernel.ubuntu.com/~jj/linux-image-2.6.35-20-virtual_2.6.35-20.30~EBSPerf_i386.deb

dpkg -i linux-image-2.6.35-20-virtual_2.6.35-20.30~EBSPerf_i386.deb

Output showed:
$ sudo dpkg -i linux-image-2.6.35-20-virtual_2.6.35-20.30~EBSPerf_i386.deb
