Self-Contained Backup for Persistent-Store

[utu]

Here's the stanza beginning at line 734 of the init of minirt.gz
...with two added lines defining a new cheatcode "restore":

# Check for updates on-disk, install them if necessary. ############## line 734
if checkbootparam "restore" then ####################### first added line
ls /mnt-system/KNOPPIX/update*.zip /mnt-system/KNOPPIX/update*.tar.gz\
/mnt-system/KNOPPIX/update*.taz 2>/dev/null | while read update; do
if [ -r "$update" ]; then
message -e "\r${CRE}${GREEN}${UPDATING} ${YELLOW}$update${NORMAL}"
case "$update" in
*.zip) ( cd / ; unzip -o "$update" >/dev/null 2>&1 ) ;;
*.tar.gz|*.taz) ( cd / ; tar -zxf "$update" >/dev/null 2>&1 ) ;;
esac
fi
done
fi ########################################## second added line

With this modification to initrd.gz, we could change the backup routine
to save update.tar.gz to /mnt-system/KNOPPIX/, and leave it there.
It would be activated only by the cheatcode "restore" and the update
could remain in place and not require moving it around.
