Hrm, I thought I had fixed this ...

dkms baffles me sometimes. I'll take a deeper look.

Okay, Michael-

This is a nasty one ...

kvm-source is going to need the linux-headers for the kernel you're currently running, as well as any others you have installed.

A distro-upgrade (or anytime you're upgrading the kernel, too) compounds the problem. You're running one kernel, but you need to ensure that you have the headers for the new kernel too.

I'm going to sort-of alleviate the problem in kvm by adding a dpkg --status check for linux-headers-`uname -r`, and if not present, then print an informational statement about the problem, and recommend a command that will install the required dependencies.

I'm going to also set this bug as affecting dkms, and add a suggestion there too.

:-Dustin

Mario-

What would you think about dkms depending on all of:
 linux-headers-rt, linux-headers-virtual, linux-headers-server, linux-headers-generic

For the most part, the additional headers will just install a bunch of symlinks, and should not require a bunch of additional disk space.

:-Dustin

I've attached a patch, which adds
 * linux-headers-rt, linux-headers-virtual, linux-headers-server
to the Recommends.

Mario, what do you think?

:-Dustin

Dustin:

I don't think that's a good idea. Because recommends are installed by
default, it will pull in a lot of headers that are not necessary on a
majority of user's systems.

I would rather see those headers as recommends for the appropriate kernel meta packages. That way if someone adds the server kernel via the meta package, they get the server headers, etc.

Mario/Tim-

You guys are going to have to duke this out ...

I'm going to mark Bug #341405 a duplicate of this one.

:-Dustin

Mario-

The downside of latching the headers onto the kernel is that it automatically adds 75MB of headers to a given install, even if DKMS is not used.

Tough one...

:-Dustin

Dustin:

Well look at it this way. Look at the rdepends of linux-headers-generic.
It's pulled in by all the desktop packages. So the argument's two sides
then end up being:

1) Add a bunch of unnecessary dependencies to *all* desktop installs that
use DKMS.
2) Add appropriate dependencies to meta packages of any possible kernel
meta, and don't need to worry about headers being installed on systems since
they are there by default now for all situations.

The issue with this is it adds 75MB to the server footprint, which is
only ~500MB to start with. I'll talk it over with the server team and
see what they think about this tradeoff.
