Hi,

I packaged a few of Intel's out of tree NIC drivers from http://sourceforge.net/projects/e1000/ as dkms based .debs and included them in a custom grml image.

I'll explain how; if there is interest, I can also share my packages (although, as you'll see, they're likely sub-par, because I did not take the time to really understand what I was doing; in particular, I fear the e1000e module may not always build correctly at grml-live time, while it builds correctly on the live system).

1. I grabbed some tarballs from http://sourceforge.net/projects/e1000/:

-rw-r--r-- 1 root root   269997 Sep  5 16:25 e1000e-2.5.4.tar.gz
-rw-r--r-- 1 root root   303648 Sep 17 02:23 igb-5.0.6.tar.gz
-rw-r--r-- 1 root root   362747 Sep 30 23:21 ixgbe-3.18.7.tar.gz
-rw-r--r-- 1 root root   140096 Sep 30 23:31 ixgbevf-2.11.3.tar.gz

2. I extracted each.

3. I moved the contents of foo-1.2.3/src to foo-1.2.3 itself in each.

4. I created a dkms.conf like the following in the root of every driver root directory (i.e. foo-1.2.3/):

AUTOINSTALL="yes"
BUILT\_MODULE\_NAME\[0\]="igb"
CLEAN="make clean"
DEST\_MODULE\_LOCATION="/updates"
DEST\_MODULE\_NAME\[0\]="igb"
PACKAGE_NAME="igb"
PACKAGE_VERSION="5.0.6"

5. I made sure the Makefiles get the kernel version to build for from the KERNELRELEASE ennvar (not BUILD_KERNEL or similar), because this is what dkms sets:

sed -i 's/BUILD_KERNEL/KERNELRELEASE/g' Makefile

(In at least one case, I also replaced an #ifdef CONFIG_PM_SLEEP with #ifdef CONFIG_PM in netdev.c because the module didn't build for my kernel otherwise, but this problem doesn't manifest with the grml kernel because it defines either both or neither.)

6. I issued the following dkms commands (from the source directories):

dkms add -m foo -v 1.2.3
dkms mkdeb -m foo -v 1.2.3 --source-only

(Naturally, you have to replace 'foo' with the name of the module and 1.2.3 with the actual version number.)

The second command will create a .deb and dump it somewhere under /var/lib/dkms/.

7. I imported the .debs into my private repository (managed by reprepro).

8. I installed grml-live. I created a new fai 'class', called EXTRANIC. This involved creating the following files:

/etc/grml/fai/config/hooks/instsoft.EXTRANIC (mode 755):

#!/bin/bash
set -u
set -e
. "$GRML\_LIVE\_CONFIG"
$ROOTCMD apt-get --yes --force-yes install \
	dkms build-essential linux-headers-3.10-1-grml-amd64

(You'll note this is inelegant because it hardcodes the kernel version; the point here is to make sure the kernel-headers are already installed by the time the driver packages are installed.)

/etc/grml/fai/config/scripts/EXTRANIC/50-dkms (mode 755):

#!/bin/zsh
set -u
set -e
. "$GRML\_LIVE\_CONFIG"
for kernelversion in $(${=ROOTCMD} sh -c 'ls -1 /boot/vmlinuz-*' \
	| sed '[s at .](http://ml.grml.org/mailman/listinfo/grml)*boot/vmlinuz-@@'); do
		echo "Building dkms modules for kernel $kernelversion."
		${=ROOTCMD} /etc/kernel/postinst.d/dkms "$kernelversion"
done

(This may not be necessary. It attempts to build all dkms modules once more, after all requested packages have been installed.)

/etc/grml/fai/config/package_config/EXTRANIC:

e1000e-dkms
igb-dkms
ixgbe-dkms
ixgbevf-dkms
broadcom-sta-dkms
r8168-dkms

(Yeah, so not just Intel. The others come from regular Debian.)

/etc/grml/fai/config/files/etc/apt/sources.list.d/myrepo.list/EXTRANIC:

(Contains the deb http://... line for my repository.)

/etc/grml/fai/config/package_config/ZFSONLINUX.asc:

(Contains the public key of the repository signing key; I'm not sure this is really the correct way of injecting it in the build process.)

9. In /etc/grml/grml-live.local, I have:

OUTPUT=/tmp/grml/grml-live SUITE="sid" FAI_DEBOOTSTRAP="sid http://cdn.debian.net/debian" VERSION=$(date +%F) RELEASENAME="grml64-extranic" GRML_NAME="grml64-extranic" HOSTNAME="grml-extranic" ARCH="amd64" DISTRI_NAME="grml-extranic" NO_ADDONS_BSD4GRML='1' EXIT_ON_MISSING_PACKAGES='1' DEFAULT_BOOTOPTIONS="ssh=sekrit" # Be sure you understand what this does before using it

10. I built a new iso using the following command:

echo 'y\nn\ny\ny'
| env -u TMPDIR -u TMP
nice -n 20
grml-live -A -u -e /path/to/grml64-full_sid_20131001.iso
-c DEBORPHAN,GRMLBASE,RELEASE,AMD64,IGNORE,EXTRANIC

I'm posting this in the hope someone finds it useful. I'm not subscribed to the list, so please Cc: me on replies.

The resulting image is larger than regular grml as it includes build-essential and its dependencies; if that's a problem, I suppose you can add a script after 50-dkms that purges now-unneeded packages.

Incidentally, zfsonlinux can be added to grml in much the same way (that was the original point of the exercise for me).
