Re Knoppix as Ghost

Hello all,

I found this post on /. and thought that it had a lot of potential uses.

Quote:

You don't need any stinking non-Free software to make ghost images.

Here's how you do it:

0. Set up a recipient (either a second hard disk, a machine on the 
network - whatever - I do it over the network)
1. Boot Knoppix on the machine you want to ghost.
2. Mount the destination.
3. dd if=/dev/hda bs=128K | gzip > /path/to/image.gz

To restore:
0. Set up the source.
1. Boot Knoppix on the machine you want to install.
3. Mount the source.
4. gzip -dc /path/to/image.gz | dd of=/dev/hda bs=128K

Tips: Overwrite any free space on the machine you want to ghost with a 
huge file filled with 0x00, then delete the file. The disk image will 
compress much better as you've scrubbed the deleted files.

I use a system like this to ghost many machines at a time (an image 
server can easily deal out 30+ images at once). It'd cost a fortune to 
license many copies of ghosting software - with Knoppix and a very small 
shell script, I've got an automated system which will do many machines 
at once. (A typical 40GB fresh WinXP install with our apps compresses to 
under 1GB with gzip).
If you're doing WinXP, remember to either make a Sysprep build or use 
something like System Internals free (open source but not truly free) 
tool to change the SID and hostname of the machine when it's booted the 
first time. (This is the approach we use due to the limitations of sysprep).
