Release Notes for grml-medium 2010.04 - codename Grmlmonster
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. 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 2.1 GB of software on a ~700 MB ISO and grml-small is a flavor with only ~100 MB ISO-size, grml-medium tries to close the gap between those two flavours providing an ISO with ~200MB. It does not provide all the software shipped with normal/big/large grml but provides essential stuff, a full featured kernel and the X.org server. 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.
New features
Special new features:
- vnc bootoption: booting with vnc=yourpassword and the startx bootoption automatically starts the vnc service for user 'grml' using graphical remote access with provided password
- dmraid related bootoptions: nodmraid to not enable present dmraid devices, dmraid=on to automatically enable any present dmraid devices and dmraid=off to actively try to stop any possibly present dmraid devices.
- New bootoption bootid for improving reliability of boot process. The specified argument to the bootoption is matched against a token on the ISO to make sure that only the correct Grml version gets booted.
- More robust network booting: The last Grml release (2010.04) already invented the ethdevice= bootoption which allows you to specify a specific NIC for booting. The bootoption ethdevice and its surrounding code has been extended so it is possible to specify multiple devices at once that should be configured. If you don't have any specific configuration all present NICs will be used for configuration via DHCP automatically. Visit the Grml developer blog for further information
- Providing an improved default configuration for top(1) utility when running as (non-root) user
- Improved serial console handling through /etc/inittab*. Using normal getty instead of mgetty and several baud rate settings (115200,57600,38400,19200,9600,4800,2400,1200) to let getty figure out which mode should be used.
- Reworked xinitrc handling: modularize the code into ~/.xinitrc.d/ and support configuration through ~/.config/grml/xinitrc.

Visit grml.org/kernel/ for more details regarding Grml's kernel.
Bugfixes
Fixed several bugs and issues reported on grml-medium_2009.10 @ grml-wiki and in the bug tracking system.
Important Changes
- Bootoption home has been dropped, the persistency feature present since 2009.10 replaces this option.
- Grml uses lang=en as default instead of lang=us if no 'lang' bootoption has been specified.
- CPU frequency scaling enabled on all hardware by default so it's no longer limited to laptops only.
- Grml's udev package has been dropped in favour of Debian's plain version and adding Grml specified configuration and scripts through Debian package grml-udev-config.
- As the bootoption bootid is used as default bootoption you need to make sure that you've an according and valid bootid=... entry in your kernel cmdline or use the ignore_bootid bootoption to skip the boot id check. This is especially relevant for grml2usb installations (make sure to use a recent grml2usb version) as well as booting with isofrom/findiso bootoptions from harddisks.
