# Original script by Robert Shingledecker for John Andrews Damn Small Linux
# October 2003
#
# rapidweather version 11, dated March 17, 2004
#
# This script restarts X after the file restoration, for use in Luit Linux 0.2
#
# file name is /mnt/hdb1/filetool.sh
# Normally, this script does not go in the backup directory:
# goes in the same partition as /knoppix if run from hard drive. 
# For the Foxfire version of Luit Linux 0.2
# For the slave hard drive on the Dual Pentium Pro machine.
# This drive is partitioned into 2 partitions:
# /dev/hdb1 is for the backup tarball, and the filetool.lst for the Foxfire version of Luit Linux 0.2
# /dev/hdb2 is for the backup tarball, and the filetool.lst for the MozillaFirebird version of DSL 0.6.1
# With this setup, one can restore either the Foxfire version, or MozillaFirebird version
# on a bootup of Damn Small Linux 0.6.1 with the knoppix cheatcode:
# for MozillaFirebird version, #boot: knoppix restore /dev/hdb2
# for the Foxfire version, a knoppix cheatcode does not currently work with Luit Linux 0.2.
# Luit Linux 0.2 must be started using the CDROM, as the /knoppix in /dev/hda1 is for DSL. 
#
# This script will create the /storage directory in the Luit Linux filesystem for backup/restore.
# carefully modify this file to mount  the /storage directory on the  partition you want to use. 
#
# Here is the partition I am using: 
# using /dev/hdb1, a ext2 linux partition. 
# put this in line 40 below:
# 
# A simple script to save/restore configs, directories, etc defined by the user
# in the file filetool.lst
# Upon first successful run of this script a default filetool.lst will be
# copied to the BACKUP_DEVICE. Then the user can control which files/dirs will
# save/restore
#
HOME=/home/damnsmall

# In the luit linux installation, the following reference to a storage directory is not used,
# but is allowed to run anyway, as it is harmless. To restore this system in the first place,
# one has to mount /dev/hdb1, and then navigate to it to run this filetool.sh script.
# As mentioned above, this file is usually run from the already mounted /cdrom
# directory, because the /knoppix folder is there. filetoool.sh is in the same partition
# as the /knoppix folder, and becomes /cdrom in the DSL/Luit Linux filesystem.
#
# Because it might exist, I am going to un-mount and remove the Storage directory
# so this script can proceed normally.
