-grml2ram Copy grml's squashfs file to RAM and run from there
+grml2ram Copy Grml's squashfs file to RAM and run from there
grml toram Copy the whole CD/medium to RAM and run from there
grml toram=filename.squashfs Copy the specified file to RAM and run from there
Usage example: grml toram=grml-medium.squashfs
Notice: grml2ram is an alias for this option which
corresponds with the grml flavour settings by default
-grml tohd=/dev/sda1 Copy grml's squashfs file to harddisk partition for later
+grml tohd=/dev/sda1 Copy Grml's squashfs file to harddisk partition for later
use via "grml bootfrom=/dev/sda1"
grml bootfrom=/dev/sda1 Use the squashfs file from directory 'live' of the specified device
Setup can be done booting 'grml tohd=/dev/sda1' or
grml findiso=/grml_2010.04.iso Look for the specified ISO file on all disks where it usually
looks for the .squashfs file (so you don't have to know the device name
as in isofrom=....).
+grml fetch=$IP/filename.squashfs Download a squashfs image from a given url, copying to ram and booting it.
+ Due to current limitations in busyboxs wget and DNS resolution, an URL
+ can not contain a hostname but an IP only.
grml live-media-path=live Sets the path to the live filesystem on the medium
By default, it is set to /live
