Release Notes for grml-small 2009.10 - codename Hello-Wien
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. You can use Grml (for example) as a rescue system, 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 CD.
Whereas Grml provides about 2 GB of software on a 700 MB ISO, grml-small is a flavor with only ~100 MB ISO-size (~275 MB uncompressed). It does not provide a lot of software but the essential stuff for being a rescue system on a business card CD-ROM or a small USB device. You can use the Debian package management system to install software on the fly (assuming you have network access to a Debian mirror). Take a look at the 'Debian-Information'-section if you are searching for the package list.
Special new features:
- vesamenu bootsplash: this graphical bootsplash version (see screenshot on the right) provides an easy to use boot selection menu.
- dd-able ISO: the ISO can be installed to a device directly using dd(1). This means you can run (warning: overwrites any existing data) 'dd if=grml.iso of=/dev/sdX' on your USB pen and will get a bootable grml system. This method isn't as flexible as the grml2usb approach but might be useful if you don't have a working grml2usb setup.
- Added addons which where previously shipped only with the grml and grml-medium flavours.
- Integration of Etherboot/gPXE. In the Addons submenu of the bootsplash you can directly invoke Etherboot/gPXE.
- Integration of Grub. In the Addons submenu of the bootsplash you can directly invoke Grub1 and Grub2.
- bootoption ethdevice: use specified network device for network booting (PXE) instead of default (being eth0). Feature contributed by Helge Wagner. Usage example: ethdevice=eth1
- bootoption netscript: use this parameter to download and run a script from a specific location. Supports variables like $HOSTNAME, $ARCH, $KERNEL to download host specific software. Usage example: 'netscript=example.org/$HOSTNAME/startup-script' 'netconfig' has been adjusted to also support this variables.
- DNS info as hostname: the hostname of the live system will be automatically set to the information retrieved via DHCP/DNS (if present). This feature can be disabled using the nodhcphostname bootoption. Feature contributed by Andreas Thienemann.
- reworked configuration framework: the so called DCS feature (debs, configuration and scripts) provides a more consistent configuration for bootoptions like scripts, netconfig, debs,.... The DCS directory defaults to the root directory of the live image. If a file system labeled GRMLCFG is found, the DCS directory is the root directory of that file system. Alternatively, the myconfig boot parameter can be used to directly specify a device which is then taken as DCS directory (myconfig=/dev/sda1, for example). The documentation of the behavior up to Grml 2009.05 is documented as well as the behavior in current Grml versions. Special thanks to Marc Haber for his work.
- grml-autconfig configuration: support for overwriting values via /etc/grml/autoconfig.local has been added, so configuration changes are possible without running into file conflicts on upgrade.
New features in Grml's Zsh
- grml zsh documentation: grmlzshrc(5) is a manpage providing detailled information about grml's zsh configuration. On the grml system it is available offline via 'man grmlzshrc'. An online version is available as well. Special thanks to Joerg Woelke for his work.
- Directory specific shell configuration with Zsh: based on directories you can set your own profiles. Further details available online.
- Using history-incremental-pattern-search-* for incremental history searches per default (via ^r and ^s). Press ctrl-r to search in the history using the specified pattern. For example you can type 'cd*grml' for searching command lines containing 'cd ~/devel/grml2usb' or 'cd ~/git/grml-live. You can iterate through the results as usual too retyping ^r or ^s.
- grml-exec-wrapper: simple but smart program execution wrapper. This script is for executing commands but check whether the specified program is available at all. If the command is not available an error message is displayed either on the command line (if $DISPLAY is empty) or as graphical version (if $DISPLAY is set).
- grml-sniff: script for configuring a network sniffing setup.
grml2usb (install grml ISO(s) on usb device for booting):
- using syslinux as default bootmanager (grub available only as option using --grub)
- support for new vesamenu bootsplash, including support for multi-ISO setup
- adding additional ISOs to an existing grml2usb installation is possible (specifying different default boot options is possible as well)
- grml2iso (tool to create a multiboot grml ISO using grml2usb) supports vesamenu bootsplash, altering of bootoptions and removing existing boot parameters. grml2iso also supports copying files to the generated iso (easy remastering for common usecases).
grml-debootstrap (wrapper around debootstrap for installing plain Debian via grml):
- new cmdline option for specifying target architecture (--arch)
- use cdn.debian.net as default mirror
- several bugfixes and more updates... check out the Debian changelog for details
Visit grml.org/grml-debootstrap/ for more details regarding grml-debootstrap.
Based on vanilla kernel 184.108.40.206 including several patches and the aufs module.
Visit grml.org/kernel/ for more details regarding the grml-kernel.
- Use of Debian Geo Mirror: Grml uses cdn.debian.net as Debian mirror in the sources.list setup nowadays. This should select a mirror near to the location of the user, so the default Debian mirror in Grml is no longer a server from Germany only. Visit the Debian Wiki for further information.
- Use of sources.list.d: the Debian mirror configuration moved from /etc/apt/sources.list to the directory /etc/apt/sources.list.d/. The Grml mirror configuration can be found in /etc/apt/sources.list.d/grml.list and the Debian mirror configuration is located in /etc/apt/sources.list.d/debian.list.
