Ok,
This restore disk works for the situation in the previous post.
If you need it to work for your own custom setup, you'll have to change the script to reflect your own ideas.
I used VMware on my Ubuntu installation (on my main machine) to mess about with the remastering process so I wouldn't tank my dsl install on the old laptop.
So before I began all of this I had the following files already created and copied to a shared folder on my Ubuntu machine:
hda1backup.tar.gz ---this file is the result of doing the automatic backup on the previous post. It can be found on hda3 in the root directory.
hda3backup.tar.gz --- which I made after i had my automated system backup in place and working properly by doing the following in terminal on my hda1 dsl on the laptop.
| Code Sample |
sudo su
mkdir /hda3
umount /dev/hda3
mount /dev/hda3 /hda3
cd /
tar -cvzpsf /hda3backup.tar.gz hda3
|
MBRbackup.bin ---located on the root directory of hda1, which I made by doing the command
| Code Sample |
sudo dd if=/dev/hda of=/MBRbackup.bin bs=1 count=512
|
from the hda1 dsl terminal of the laptop.
I ended up taking my remastering instructions from the page below.
http://www.linuxforums.org/desktop....le.html
Most of the instructions weren't needed for my project, so I'll repost the steps below that I actually used.
I booted up to the dsl live disk iso in vmware with a virtual harddrive on IDE 0:1 that was formatted to ext2 for partition 1 and had enough space for the operation. As well as a swap partition for the live disk session to use on hdb2. The live disk should pick up the swap partition automatically.
I used hdb so it wouldn't confuse me with the backup operations which deal with "hda1"
To figure out how much space you need on hdb1, take the total size of your backup files and double it, and then add another 150 to 200 megs.
Here I cheated a little and did the partitioning of the virtual hard drive by loading up the virtual machine with an iso of Puppy Linux and using Gparted, but if you're familiar with partitioning using DSL, then more power to you.
If you're going to do this in a real situation (not in VMware) then you'll have to adjust the instructions below to reflect the actual partition you're going to use instead of hdb1, and the Samba portion of the instructions won't be necessary as you can just boot to your normal linux installation and burn the iso. So adjust this stuff as you need to for your specific case.
Ok... once the live disk is booted up, open up a terminal and put in the following commands.
| Code Sample |
sudo su
mkdir /hdb1
mount /dev/hdb1 /hdb1
cd /hdb1
#note that from here on out everything is done from /hdb1 directory
mkdir source newcd newcd/KNOPPIX
cp -Rp /cdrom/boot newcd
cp -Rp /cdrom/lost+found newcd
cp -Rp /cdrom/index.html newcd
cp -Rp /KNOPPIX/* source
cp -Rp /KNOPPIX/.bash_profile source
|
Ok, at this point, the /hdb1/source directory contains the same info as whats on the original live disk.
So at this point, I minimize the terminal.
I download the samba.dsl extension from MyDSL so I can copy my backup file from where I saved it on my desktop machine.
I mount up my samba share, then open emelfm in root mode.
In the left panel I browse to my mounted shared folder, and in the right I go to /hdb1/source. The next step is to make a directory right pane called "backup" then enter it.
I then select my hda1backup.tar.gz file from the left pane and copy it to the right pane.
I do the same for hda3backup.tar.gz and MBRbackup.bin.
Once that is done, minimize emelfm as we'll use it again in a moment.
Now I open Beaver in root mode. Root mode may not be necessary, but it didn't hurt.
Using Beaver in root mode, open up /hdb1/souce/opt/bootlocal.sh
add the following line to it
| Code Sample |
sudo /KNOPPIX/backup/CDbackup.sh
|
save it, and then open a new file.
Here' where the script comes in... its pretty big AND IT IS FINALLY COMPLETE!
If you wish to customize this process, this script is where to do it.
in the new file put the following:
| Code Sample |
#!/KNOPPIX/bin/bash

Ok, once all that is in the untitled text file, in Beaver you need to save it as /hdb1/source/backup/CDbackup.sh
Then bring emelfm back up and change the newly made text file's permissions to be executable by right-clicking backup.sh and selecting "Properties" then "Permissions" and pushing in the "exec" buttons and hittin apply or ok or whatever.
Now minimize emelfm again.
Ok, now its ready to be made into an ISO.
So we go back to the terminal which should still be parked at /hdb1.
put in the following two commands.
be advised it takes a little while.
| Code Sample |
mkisofs -R source | create_compressed_fs – 65536 > newcd/KNOPPIX/KNOPPIX
|
| Code Sample |
mkisofs -no-pad -l -r -J -no-emul-boot -boot-load-size 4 –boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o mydsl.iso newcd
|
When its done, it should poop you out a file called mydsl.iso in your /hdb1 directory.
Bring emelfm back up. The left pane should still show your samba shared folder. So just change the right pane to show /hdb1 and move your new ISO over to your shared folder.
Its is at this point that I made my snapshot in VMware.
At this point you can exit vmware and burn your new ISO.
When booting from the new disk, it never comes fully up to X, everything happens before that. You do have the option though of booting on up to the live session if you like.
The backup.sh script is pretty well commented.
If you have any more questions about it, please feel free to ask.
If you discover any typos, lemme know asap if you please 
In the next post I'll post every script I have that is involved with this process.
