-The following kernel options are available (do NOT use them as 'grml $OPTION',
-use them as '$OPTION'!):
+These options work from the isolinux bootprompt of Grml based (live) systems.
+(Do NOT use them as 'grml $OPTION', use them as '$OPTION'!):
grml Use default settings (same as just pressing return)
grml2ram Copy Grml's squashfs file to RAM and
serial Activate ttyS0 and start a getty
grub Boot Grub bootloader (special all-in-one-image)
dos Boot FreeDOS
-bsd Boot MirOS BSD
hdt Boot Hardware Detection Tool (from syslinux project)

The following boot options can be combined.
Notice: not all of them are available on all the Grml flavours.
grml lang=at|de|cn|da|es|fr|it Specify language ($LANG, $LC_ALL, $LANGUAGE - utf8) + keyboard
grml lang=nl|pl|ru|sk|tr|tw|us Specify language ($LANG, $LC_ALL, $LANGUAGE - utf8) + keyboard

By default, it is set to /live/$GRML_FLAVOUR/ (where $GRML_FLAVOUR
is corresponding to grml64-full, grml32-full, grml64-small,...
[Note: this option is mandatory since release 2011.12]
-grml nostats Don't send any information to the Grml project at startup.
- Parameters sent are Grml version, if the cpu supports 64bit,
- anonymized boot parameters and boot source (remote or local).
- [Note: only available since release 2011.12]
grml module=grml Instead of using the default "$name.module" another file can
be specified without the extension ".module"; it should be placed
on "/live" directory of the live medium
display shell code being executed in initramfs.
grml debug=noscreen Get shells during process of booting, verbose, but without using GNU screen
grml nocolor Disable colorized output while booting
+ Also set SYSTEMD_COLORS=0 to disable colors in systemd output
grml log Log error messages while booting to /tmp/grml.log.`date +%Y%m%d`"

grml testcd Check CD data integrity and md5sums
grml dmraid=off Actively try to stop any present dmraid devices.
grml nolvm Disable scanning for Logical Volumes (LVM)
grml lvm Automatically activate Logival Volumes (LVM) during boot
-grml readonly Make sure all harddisk devices (/dev/hd* /dev/sd*) are forced to read-only mode
+grml read-only Make sure all harddisk devices (/dev/hd* /dev/sd*) are forced to read-only mode
grml ethdevice=... Use specified network device for network boot instead of default (eth0)
grml ethdevice-timeout=... Use specified network configuration timeout instead of default (15sec)

Installation related settings:
------------------------------
target= target partition/directory of the new Debian system, e.g.: target=/dev/sda1
grub= where to install grub to, e.g.: grub=/dev/sda
release= specify release of new Debian system (default is stable), e.g.: release=sid
- mirror= specify mirror for apt-get/aptitude, e,g.: mirror=http://cdn.debian.net/debian
+ mirror= specify mirror for apt-get/aptitude, e,g.: mirror=http://ftp.debian.org/debian
password= set passwort of user root without prompting for it, e.g.: password=AiTh5ahn
Usage example for automatic installation:
- debian2hd target=/dev/sda1 grub=/dev/sda mirror=http://cdn.debian.net/debian password=foobar
+ debian2hd target=/dev/sda1 grub=/dev/sda mirror=http://ftp.debian.org/debian password=foobar
