-Any additional argument(s) to grml-live will be given to the FAI commandline
-(being basically "fai dirinstall ...). This might become a temporary solution
-(due to security reasons), if you need an option please let us know so we can

How to get your own live-cd - the easy, fast and simple way
-----------------------------------------------------------
-To get a small, Debian-stable and grml based live-cd:
+To get a small, Debian-stable and grml based live-cd using /dev/shm/
+as build and output directory:
- # TARGET="/grml/grml_uncompressed"
- # CDDIR="/grml/grml_cd"
- # grml-live -c GRML -t $TARGET
- # mksquashfs $TARGET/* $CDDIR/live/grml.squashfs -noappend
- # cd $CDDIR
- # mkisofs -V "my personal grml" -l -r -J -no-emul-boot -boot-load-size 4 \
- -boot-info-table -c boot/isolinux/boot.cat \
- -b boot/isolinux/isolinux.bin -o /grml/grml.iso .
+ # grml-live
+
+[NOTE]
-(TODO: provide the content of /grml/chroot/grml_cd through the package
-grml-live, in the meanwhile get the content from a current grml-ISO)
+If you have about 700MB of free space inside /dev/shm (being a tmpfs, usually
+you have >=1GB of RAM) just run "mount -o remount,suid,dev,rw /dev/shm" and use
+/dev/shm as build and output directory - resulting in very fast build process.
+But please be aware of the fact that rebooting your system will result in an
+empty /dev/shm, so please another directory for $CHROOT_TARGET, $BUILD_TARGET
+and $ISO_TARGET if you plan to create more persistent output. :)
