 This directory is used to build a USB key containing a Kubuntu 8.04 LiveCD
 with persistent OS files and persistent /home files.
 
+
+Start by editing the "config" file. Be sure to get your USB_DEV
+definition correct.  The scripts you need to partition the key and 
+to write the boot image to it are all in this (usb) directory. 
+
+After editing the config file, run:
+
+  ./partition_usb_key
+
+Note, this script assumes that you have a 3GB or bigger key.  It
+may work for a 2GB key, but you might want to reduce the size of
+the second partition.
+
+This script creates three partitions:
+
+ 1. kubuntu8  -- USB boot partition containing the OS
+ 2. casper-rw -- A writable ext3 partition for saving OS changes
+ 3. home-rw   -- A writable ext3 partition for saving /home
+
+When the key is booted, assuming you choose the first option 
+(LiveCD), you will be running as user "ubuntu" the password is
+"bacula", and you will be in /home/ubuntu.

+
+====
+
+The directory "remaster" contains the scripts that allow picking
+apart a Kubuntu Hardy ISO and then updating and recombining the
+parts into a USB boot image.  The information below is somewhat
+low level and should not be needed unless you want to do your
+own remastering either starting from the Kubuntu release or from
+the Bacula remastered release.

 Note, the sqfs.tar.gz is the whole squashfs unsquashed.
