Release Notes for Grml 2010.12 - codename Gebrüder Grml
About
Grml is a bootable live system (Live-CD) based on Debian. It includes a collection of GNU/Linux software especially for system administrators and users of texttools. Grml provides automatic hardware detection. Grml is the perfect rescue system, but you can also use it for analyzing systems/networks or as a working environment. It is not necessary to install anything to a harddisk; you don't even need a harddisk to run it. Due to on-the-fly decompression Grml includes about 2 GB of software and documentation on the live system.

New features
- New Linux kernel version based on 2.6.36.2
- Config-less X to take advantage of X.org's automatic configuration
- Support for Kernel Mode Setting (KMS)
- grml-rescueboot / loopback.cfg feature and grub-imageboot for ISO boot (more details available in 'Booting ISO images from within GRUB2')
- Initial release of Kantan, an automated testing suite for continuous integration and a test environment; see grml.org/kantan/ for details (not shipped in Grml by default though)
- Incremental grml-rebuildfstab triggered by udev events for faster execution time
Special new features:
- Improved serial console on multiple devices (thanks to Marc Haber)
- vnc_connect bootoption allowing to connect to an existing listening vnc client. Can be used to connect easily from devices behind firewalls as connection is initiated from the vnc server instead of the vnc client.
- grml-terminalserver no longer needs to rebuild the initrd, default initrd/initramfs shipped on ISO is fully-featured for PXE boot.
- The netscript bootoption provides the new environment variable named NETSCRIPT to provide an option to ensure that the script is executed under the according environment.
- Updated manifold boot features (thanks to Thorsten Glaser): dd-ed ISOs (for booting via USB) now use isolinux as bootloader as well, so you get the same boot menu in normal CD boot as well as in USB boot.
New features in Grml's Zsh
- Fully documented, see grml.org/zsh (thanks to Joerg Woelke) - available online as well as offline ('man 5 grmlzshrc')
- Uses zsh's built-in vcs_info and falls back to a grml-packaged version if the current version of zsh does not come with its own implementation
Important Changes
- Removed many window managers (fvwm/fvwm-crystal, ratpoison, dwm, twm, w9wm, evilwm, jwm, pekwm) due to size and out-of-the-box configuration issues. See issue897 for the discussion.
- grml2hd is no longer available from grml-quickconfig, the selection dialog displayed after grml-full or grml-medium are done booting.
- Reworked /etc/runlevel.conf deployment. Instead of providing runlevel.conf through grml-etc it's being deployed through grml-live to improve customization capabilities.
- Rewrite of grml-x due to new xorg.conf handling, please note that some options that are now unnecessary have been removed and that all single-dash options (-force, -nostart,...) became common long options (--force, --nostart,...).
- Switched from live-initramfs to live-boot based on version 2.0.12.
- Switched from pump to ISC dhclient, triggered by udev events during boot (use nodhcp to turn this off).
- Network configuration via /etc/network/interfaces supported during boot-up (static IP address assignment - e.g. via ip=... booption - and dhcp are both configured via /etc/network/interfaces).
- Reworked sound mixer handling to improve handling of IBM hardware and multiple soundcards.
