Good Morning,
How do I update a *.squashfs file? I have Kali Linux 1.0.6 Debian Wheezy based live, I know how to extract the filesystem.squashfs files but I wish after installing Kali Linux and doing apt-get update && apt-get upgrade, so next time when I use the live DVD again I won't have to do apt-get update && apt-get upgrade again I mean if my Kali Linux is the latest with the latest packages versions I pack the system in squashfs and make a new fully upgraded ISO file
I hope you undertand what I mean because I am a non English speaker
Thank you very much for your answers

# mount -t squashfs -o loop image.iso /mnt

And then rsync, tar, or whatever the filesystem to a partition. There's also unsquashfs that could be used for that. Bear in mind that a 2GB squashfs iso might expand to an 8GB install. And you'll need to point a bootloader at it's new home and maybe update /etc/fstab to know it's new location if it exists.
