Great news. Now I'm part of the Robocup team "Mostly Harmless" at Graz University of Technology, Austria. I will be working on kernelstuff, building debian packages and doing hardware recognition using grml technologies. An embedded system will be used with hardware like a CAN Dongle, compact flash cards, WLAN, serial connection and so on. This means I will work on grml as part of my studies at university at least for this semester.
Thanks to Mabu for his investigations!

I'm preparing the development release for the upcoming grml 0.5 release. As we have a kernel upgrade in this release (using 2.6.13-grml) and I'm still lacking hardware using SCSI-controllers for booting I request your help. If you have access to a computer which is able to boot via SCSI please help me. You just have to send me the file '/proc/pci' and which module is used for the device (if you don't know which one is used just send me output of 'lsmod' and the kernel configuration). Just drop me a mail (mika [at] grml.org), your help is appreciated!

We just have a developer meeting in Graz and Gebi wrote a script namend grml-vpn. grml-vpn is a program to establish encrypted communication channels in a network. We just tested it and it really rocks. :-) It's very easy to use, take a look at the usage example:
Gebi (root@gebi) starts grml-vpn on his laptop with key/passphrase 'test' and uses his and my ip for the encrypted communication channel:
root@gebi # grml-vpn -k test add 1000 192.168.1.104 192.168.1.101
I (root@mika) am using the same command line on my laptop:
root@mika # grml-vpn -k test add 1000 192.168.1.104 192.168.1.101
To demonstrate that it's working let's use IPsec's setkey command:
root@mika # setkey -D192.168.1.101 192.168.1.104
Now let's check whether it's really encrypted:
root@mika # ping 192.168.1.104

fullautomatic grml-installation Posted by Michael Prokop in packages at 19:06
I just implemented the code for running grml2hd in full automized mode. This means you can run:
# GRML2HD_NONINTERACTIVE=yes grml2hd
... drink some coffee and some minutes later - without any further interaction - you have a full functional linux system on your harddisk. Configuration of grml2hd is possible via /etc/grml2hd/config. You can even run pre- and post-commands to partition your harddisk automatically, run upgrades without interaction or whatever you like.
Now I will implement a bootoption 'grml2hd' which allows booting and installing grml without any further interaction right out of the box. This means it will be possible to set up a cluster of - let's say for example - 30 computers in a computer lab without any further interaction just via using grml with grml2hd and grml-terminalserver.

grml: laptop optimization - grml-laptop Posted by Michael Prokop in packages at 11:49
Hardware recognition of grml is quite stable. But there exist are some laptops which require deep woodo and magic to work as intented to. Some laptops provide additional hotkeys and specific resolutions which might not work right out-of-the-box. Therefore I just created the package grml-laptop:
grml provides a hardware recognition system right out
I will add a cheatcode laptop=... for using those scripts. So if you would like to see a script for a specific/your laptop: please contribute!

grml2hd with reiser4-support Posted by Michael Prokop in general at 16:35
root@grml ~ # mount
Yes, that's grml running on a reiser4-partition. I had some problems with lilo out-of-the-box but I'm looking forward to get a full working version into grml2hd. :-)

2.6.13-grml working with unionfs Posted by Michael Prokop in kernel at 00:51
Good news! I just booted 2.6.13-grml with unionfs working. Thanks to Dave Quigley and the other unionfs-guys for their work! That was a very important step for current state of grml. Today (14th of september) we will have a developer meeting in Graz and a new devel-release should be available really soon now. There's only one release-stopper left, that's the new config-framework. People out there: we are coming closer to grml 0.5. :)

install plain Debian via grml Posted by Michael Prokop in general at 18:59
I just created a new tip named "Install (plain) Debian via grml" in the grml-wiki on the tips-page. It's a short (example) guide how to install a plain(!) Debian system via grml and debootstrap. I just tested it on my box using the current grml-small-snapshot. Rocks :-)
Sunday, September 11. 2005
I just created a package namend grml-fixes. From the package description:
This package includes some fixes for the grml system. There are for example some problems with (upstream/debian) shell scripts and the zsh. Therefor this package fixes them until they are fixes upstream.
Now we are again a step closer to the big goal to be once able to run 'apt-get install grml' on a plain Debian system and get a full-featured grml-system out of it. :-)

new grml2hd features, status of ... Posted by Michael Prokop in packages at 02:49
Today I worked a lot on grml2hd (the grml-installer) and it's features. First of all it's possible to use grml2hd with grml-small now. This means you can get a linux installation on a >=200MB harddisk system. ;-) I also integrated the grml-autoconfig framework within grml2hd. There's a script namend grml-autoconfig which is the interface to the grml-autoconfig framework's configuration file /etc/grml/autoconfig. And finally there are some other small improvements not visible to the user but useful for the bootup sequence. I also improved the grml-autoconfig-framework itself - some parts of the config-framework have been merged into the code. I also worked on the script mkpersistenthome and the home=...-bootparam: both are essential parts of the config-framework and have to work with grml 0.5.
Kernel 2.6.13-grml works quite fine but it does not work on the live-cd-system yet. The reason is that there's one bug left in unionfs and therefor I'll have to wait until unionfs-developers resolve the bug and release a snapshot supporting kernel 2.6.13. In the meanwhile I'm working on the config-framework...

Today I created a new page in the grml-wiki: grml on laptops
The target of the page is to collect information regarding problems with laptops. Often it's just a short commandline, bootoption or keypress which strongly improves hardware support/the situation in general with grml.
If you have some spare time please contribute!
Thursday, September 1. 2005
I just finished main work on 2.6.13-grml including all the extra modules. Now I'll update documentation on grml.org/kernel-devel/ and will integrate the kernel in chroot of grml 0.4-3. I'm running 2.6.13-grml already on my develmachine, works very fine so far.
Testing and feedback are welcome (as usual): download .debs from kernel-repository

german grml-paper available Posted by Michael Prokop in general at 11:39
A german paper about grml is available online: grml-grml.paper (170kB, PDF) That's 24 pages about technologies used at grml and some main information about grml itself. Feedback welcome!
BTW: If (upcoming beta-tester) Carl St-Jacques reads this entry: please contact me with another e-mail address. I can't reach you with the provided one (connect to mx.francolinux.ca[188.8.131.52]: Connection timed out). Thanks.

2.6.13-grml and status information Posted by Michael Prokop in general at 10:58
Currently I'm working on shortening the todolist. Nearly no serious issues are left, just some improvements on some scripts have to be done. grml2hd needs to be extended and the grml-configframework is the last release stopper. Now I'm working on 2.6.13-grml:
mika@grml ~ % uname -a
It supports squashfs, reiser4 and vesafb-tng already. If everything goes fine with all the extra-modules (ipw, ndiswrapper,...) I will ship grml 0.5 with 2.6.13-grml.
BTW: I've a new developer machine now: a Samsung X20 XVM 1600 V laptop.
