Howto Squeeze Reaver Pro onto a CD

The following commands will shrink ReaverPro resulting in a hybrid ISO, that can be burned to a 700MB CD, or written to a USB stick via dd (without the need for other tools).

I've managed to get it down to 652MB, and more can be squeezed out. I know I'm not the first to try this, but I posted my technique in case others want to follow.

Cut and paste these commands, especailly when in the chroot environment. Do not run as a script, for now. The apt-get lines, in particular, need to be pasted one by one, or some packages will remain.

This took me a while to figure out, so I hope you guys enjoy it.

Code:

Select All

mkdir iso
R="/media/MacHD/Users/$USER/Downloads/Reaver Pro and Xiaopan OS/ReaverPro.iso"
sudo mount -o loop "$R" iso
sudo rsync --exclude=/casper/filesystem.squashfs -a iso/ dvd
sudo unsquashfs iso/casper/filesystem.squashfs
sudo umount iso
sudo rmdir iso
 
 
# Enter chroot
sudo mount --bind /dev/ squashfs-root/dev
sudo chroot squashfs-root
# The following is typed in the chroot env:
mount -t proc none /proc
mount -t sysfs none /sys
mount -t devpts none /dev/pts
export HOME=/root
export LC_ALL=C
export PS1='\[\033[0;31m\]\u@\h$PWD\[\033[0m\]\[\033[0;36m\]\[\033[0m\] '

cd ..
 
sudo mkisofs -J -R -l -f \

I'm glad you like it. I'm still tweaking, and just updated the commands. I now almost got it working as a script. Also, for an ultra small ISO I might try getting it to work with slitaz.

--- Double Post Merged, 18 Jul 2012 ---

Here's an update of all the changes I made:

1. Removed the 30 second boot delay -- so now it boots faster and without a prompt.
2. Removed the 3 second autologin dialog box.
3. Fixed the "Could not apply stored configuration for monitors" popup notice.
4. Made it a hybrid ISO (write to a USB stick via dd).
5. Removed a bunch of unnecessary programs (boots faster and uses less RAM).
6. The ISO is now only 565MB.

I also discovered that you can run ReaverPro remotely -- just type in the IP address of the machine where it is running in your browser.

 

Thanks for the comments.

I plan to share the CD as a torrent (I need to figure it out first). But I recently also made a slitaz version, which is only about 50MB!

 

The 50MB slitaz version doesn't fully work, so that's why I never released it. I'm still trying to cut down the CD version to about 400MB, so that I can have a little space for another partition, which could also result in a persistent USB version.
