I am following the steps from this website to customize my Ubuntu image. After unpacking the clean .iso I add some files to the "remaster" and also I would like to install some apps (wireshark for example), so when the systems boots with the custom image, there is no need to install anything. I run the following script:
sudo uck-remaster-clean sudo uck-remaster-unpack-iso my.iso sudo uck-remaster-unpack-rootfs // .. add desired files to the remaster sudo apt-get install wireshark sudo uck-remaster-pack-rootfs -c sudo uck-remaster-pack-iso -g myNew.iso
However, wireshark is installed on the machine on which I am running the script, not in the remaster-root system. What do I need to modify in the script above to have the apps installed on the unpacked ISO? Is it even possible?
