Great. :)

Ok.

Great. :)

I hope you already know grml-terminalserver. :) If you don't use
grml-terminalserver the grml_netboot_package might be interesting
for you, take a look at
http://wiki.grml.org/doku.php?id=terminalserver

I don't see any problems in adding this to main grml (it's available
under the BSD license).

I just created a preliminary libewf-20060820_1-1_i386.deb package.
I'll improve some minor stuff and the final package should be
available within in the next few hours/days via the grml-repository.
So the next devel-release (see http://grml.org/beta-tester/ for
details) will very probably contain this software already.

GPL, that's fine. But it has an absolutely braindread and even
broken install script (install-air-1.2.8, 165K) and depends on
perl-tk which would need ~10MB of additional space on grml. :(

So the easiest way to run AIR is a short shellscript like
http://grml.org/tmp/get-air which does the job.  I'll add an shell
function named getair (like getskype, getgizmo, get_tw_cli,... we
already have) so it's easy to install on demand.

Is there any other software you use for your forensic work and which
should become part of grml?

The current develrelease (grml 0.8-1) already provides support for
fs-labels, so will you have to run only 'mount /mnt/$LABEL' to mount
the partition containing a filesystem named $LABEL. (The release is
available for beta-testers, if you are interested in testing just
let me know and I'll give you access to the ISO.)

Sure. :)

Installing the package on the NFS-server makes it vissible to the
NFS-client. :)

If you want to install additional software either install the
software manually, use the configuration framework (see
http://grml.org/config/ - you can run your own scripts this way) or
remaster grml (http://wiki.grml.org/doku.php?id=remastering +
http://grml.org/solutions/)

> Further I will create a forensic-page in the grml-wiki and do the doku.

I just created http://wiki.grml.org/doku.php?id=forensic so you can
drop in your stuff there.
