Turn HD install into USB install?

[RageLtMan]

Is there a way to recompress the full HD install, with all the modifications i've made to it, into the normal USB image that i can boot from anywhere?

Definitely, it is a lot of fun

This guide walks you through the important steps:

This is another way to do it (from scratch).

prowl3r's method seems to use the original ISO and updates that, is there a way to do that with the current system instead of using the ISO - i've made a ton of changes to mine and would rather not re-do it all in the chroot environment for the iso. not even sure i can.

So i set up my distro mostly correctly, i tried following the ubuntu guide, but it sets up a barebones ubuntu system instead of the BT4 system as it appears to get everything from ubuntu.com.

That doesnt seem right as the kernel version is wrong and so forth.

Since bt4 already has everything needed to boot from a USB drive, is there any way to re-compress the contents of / into iso format?

EDIT: i looked over the bt4-customize.sh script and its a bit more complex than i can quickly grasp @ this hour of night. I suppose a good amount of casper related reading is in order here. If someone's turned a full HD install with all their numerous changes into bootable casper iso that has the functionality of the original bt4-pf iso, i'd love to know how it was done .

Yes there is...

Backup you HD install with tar.
cd /

tar cvpzf backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys /

Then reboot with backtrack DVD ,insert usb flash drive and install backtrack to it.

Now shut down and pull out usb flash drive and reboot normaly ,put flash drive back in and move your backup.tgz to / of flash drive and restore backup like so.

cd /of flashdrive

tar xvpfz backup.tgz -C /

KOn_TrOLL: that won't work because there's no bootloader installed.

RageLtMan: There has been suggestions on IRC to use remastersys. I'd give that a shot.
