Prevent Kernel Update when using apt-get upgrade?

Hi there,
is there a way to prevent apt from upgrading jeffs Kernel when using apt-get upgrade command?

echo linux-image-2.6.32-5-kirkwood hold | dpkg --set-selections

should keep the update back.

Maybe it would be better to tune apt somewhere to run flash-kernel like lilo after an kernel update

The flash-kernel NEWS file says that it is called automatically by update-initramfs, so that should already happen.

i don't get it.. it was running after updating udev, but NOT if I update the kernel:

So it's called - but not always it needs to be called :(

I don't understand this either. I suggest posting to debian-arm@lists.debian.org, which should reach the maintainers of flash-kernel, as well as other knowledgeable people.

[x] solved

So does installing flash-kernel result in a usable setup on the Dockstars? That is, we don't have to run mkimage manually as it does in Jeff's install script, but just install the flash-kernel package and it'll create a bootable image? My Dockstar has been running for 24 days now, partly because I'm afraid to reboot after the initrd got updated and I ran mkimage to create a new one. :-)

If this is indeed the case, then should Jeff's install script also install the flash-kernel package so users don't have to worry about it in the future?

If you use the debian kernel and trust the debian guys&girls (I do since potato, 10 years ago - and all problems I got was because I missed to run lilo after updating a few years ago) you can add the script (and install flash-kernel) and your DS will (don't blame me if it doesn't) reboot after apt-get installs a new kernel or udev or initrd.

I won't tell Jeff things he should do anyway ;-)

Hello Oscar,

thank you very much for your advice! I can confirm after successful reboots that your proposed solution works as expected.
