[Grml] Adding packages

[Lars-Erik Helander]

I am new to grml and I hope someone would be able to help me on this topic.

I am running grml off a USB stick with a persistent home.
I am using a number of packages not available in grml so I put these
in a "debs" directory on the root of my live partition (showing up
under /live/image/debs) and use the debs boot option.
This works fine and all these packages gets installed when I boot.

Problem 1: Adding another package to the "debs" directory
Since the /live/image tree is mounted read-only I cannot add/remove
any .deb files in the "debs" directory.
What I do now is that I boot some other system than by USB booted grml
system; mounts the USB stick and copy/remove files to/from the "debs"
directory; boot from the USB stick.
I would like to be able to do this without having to start some other
system, but do this in the system booted from the USB stick.
Is there a method that would allow me to do that.

Problem 2: Avoid installation at boot
The above method (putting .deb files in the "debs" directory) is very
useful for finding out the packages you need to have. Once you know
what packages you would need than you would be better off with a
method that would not require you to install the packages on each
boot, but that these packages came pre-installed.
A natural way would be to either add these packages to the live system
package set somehow.
As I can see the live system consist of a squashfs file and a file
that points out the name of this file.
Is there a way to either extend the existing squashfs file or to add
some additional squashfs (or other fs-type) file that will be mounted
along the original squashfs file?

Kind Regards

/Lars

Persistent-root is a feature on our current roadmap.
You can play with it already using live-snapshot (which is
part of the 2008.11 release):

Hi Mika and thank you very much for your response.

The remount method looks like a nice and simple solution :)

Regarding the persistence solution, I think I would rather like to
have a solution where the installed packages are not forced to be
loaded into main memory - as I understand that the live-snapshot would
do, or ...?
Do grml have some toolchain that will allow me to either add stuff to
an existing squashfs or have the system "union mount" additional
squashfs files?

While I am asking, here is another question:
I would like to add a few lines to the file /etc/security/limits.conf
in a way that these lines are part of the file at the point in time
when the file is first accessed during boot. Shall I produce a config
(config.tbz) that contains my version of the file or should I add a
script that gets executed during boogt and that will add the lines to
the file? Any details on how to do this in the preferred way are most
welcome :)

Kind regards

Yes, the "layered module architecture" feature is actually provided by
live-initramfs itself. Check out it man pages, it is trivial to add
layered module as you wish.

So far, I have just been putting the modules that I build for slax on
top of grml, about 7 layered modules on top of grml. It works perfectly,
but they are all my home, text or script files though. I.e., no debian
packages involved in the layered modules yet.
Ref http://bts.grml.org/grml/issue523

Moreover, I've build a standalone script (by patching live-initramfs) to
give users the ability to insert modules into live system on the fly, and/
or remove them as well. I.e., anding/removing layered modules does not
have to be on boot only, but can also happen any time. Ref:
http://thread.gmane.org/gmane.linux.debian.devel.live/4464/focus=4579

I've send the patches to mika, but hasn't get around to check the latest
availability status yet.
Ref: http://bts.grml.org/grml/issue650
