CHEATCODES AND HINTS FOR GRML
==============================================================================
-These options work from the (isolinux/grub) bootprompt of Grml based (live) systems.
+Isolinux bootprompt options:
+----------------------------
-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
floppy Boot from floppydisk
hd / hd1 / hd2 / hd3 Boot from (local) primary / secondary /... harddisk
debug Get shells during process of booting for debugging
-bootchart Create chart of booting sequence in /var/log/bootchart.tgz
forensic Do not touch any harddisks during hardware recognition
serial Activate ttyS0 and start a getty
grub Boot Grub bootloader (special all-in-one-image)

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, $LANGUAGE - utf8) + keyboard
-grml lang=$LANG-iso Activate $LANG (use like in lines above) with iso-mode instead of utf8
-grml gmt Use GMT-based time (UTC=yes)
-grml utc Use Coordinated Universal Time (UTC=yes)
-grml localtime Use local time (UTC=no)
-grml tz=Europe/Vienna Use specified timezone for TZ
-grml keyboard=us xkeyboard=us Use different keyboard layout (text-console/X)
+grml utc Hardware Clock is set to Coordinated Universal Time (UTC)
+grml localtime Hardware Clock is set to local time (LOCAL), this is the default
+grml tz=Europe/Vienna Use specified timezone for TZ, defaults to TZ=UTC
+grml keyboard=us Use different keyboard layout
Configuration settings:
-----------------------
By default, it is set to /live/$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`"
and /var/log/boot
grml testcd Check CD data integrity and md5sums
grml i915.modeset=0 nomodeset Disable Kernel Mode Setting (KMS) for Intel driver.
grml nouveau.modeset=0 nomodeset Disable Kernel Mode Setting (KMS) for Nouveau driver.
grml cirrus.modeset=0 nomodeset Disable Kernel Mode Setting (KMS) for Cirrus driver.
+grml mgag200.modeset=0 nomodeset Disable Kernel Mode Setting (KMS) for MGAG200 driver.
Installation related settings:
------------------------------
directory live, containing the squashfs compressed filesystem file,
must be located in the top level directory of the CD.
-*) Caution: screensavers: Don't start vlock or any other screensaver
+*) Caution: screensavers: Don't start physlock or any other screensaver
that requires a password manually. There are no default passwords on
the live system - all accounts are LOCKED by default for security reasons.
Instead just invoke the script grml-lock which prompts for setting a
