I decided to try creating a chroot environment with a BT5r2 iso file. I'm just wanting to run Backtrack from inside Debian without having to reboot into my other partition or use vmware.
I found some documentation on how to do this with BT4 at this link:
I followed these directions perfectly down this far:
Code:
mkdir -p /root/BUILD
mv bt4.iso /root/BUILD
cd /root/BUILD/
mkdir mnt
mount -o loop BT5.iso mnt/
mkdir extract-cd rsync --exclude=/casper/filesystem.squashfs -a mnt/
extract-cd mkdir squashfs
mount -t squashfs -o loop
mnt/casper/filesystem.squashfs squashfs
mkdir edit
cp -a squashfs/* edit/
cp /etc/resolv.conf edit/etc/
cp /etc/hosts edit/etc/
cp /etc/fstab edit/etc/
mount --bind /dev/ edit/dev
chroot edit
apt-get update
apt-get upgrade
I had already gotten a bt command-line prompt, but when I ran apt-get upgrade I received this error:
Code:

I found some documentation of this error at this link.
As suggested I tried this after getting inside Backtrack:
Code:
# mount -o bind /dev /mnt/dev
# mount -t proc none /mnt/proc
The same problem remained.
Even though this link was for a phone I tried this from inside Backtrack as well:
Code:
# mount -t devpts devpts /dev/pts
# mount -t proc proc /proc
# mount -t sysfs sysfs /sys
I'm at a loss at this point so any advice would be much appreciated.
The script works and creates a modified iso fine until I added the chrootbeg and chrootend functions and executed them. I'm sorry if I did something wrong this is my first post. I uploaded entire bash script for reference or in case you want to run it to debug it is called isoremast.txt.
