Starting with Grml release 2009.05 its possible to use root persistency on grml.
This means you can store your settings and reuse them on reboot, without having
to deal with this config framework. Visit

As you probably know you can adjust boot parameters on the bootprompt. You want
to set some boot parameters permanently? That's possible via adding a directory
named 'bootparams' to the Grml ISO which has to be located at the root-directory
-/bootparams/ (note: the directory is known as /live/image/bootparams/ on a
+/bootparams/ (note: the directory is known as /lib/live/mount/medium/bootparams/ on a
_running_ Grml system then). Place a textfile inside the directory containing
the boot parameters which should be appended to default ones (this corresponds
to booting without any special parameters).

which does the job and use own of the mentioned bootparams. Let's say you have

+ mkfs.ext3 -L GRMLCFG /dev/sdX1 # warning: this destroys all data from /dev/sdX1
TIP: several filesystems provide the possibility to provide a label. For
example FAT provides this through: 'mkfs.vfat -n GRMLCFG /dev/sda1' (attention:
documentation/manpage of the filesystem you want to use.
