How would you pack a current installation of Linux to a bootable ISO image?

What I'm trying to do is have my current Ubuntu installation on a DVD and whenever I'm using a different computer, I could boot from the DVD and have my whole environment already there.

Recognize that you would need a rewritable DVD to have anything other than a LiveDVD session (transient session). An option is to save it to a flash drive, which you could use as a fully functional OS. –  fixer1234 Dec 16 '14 at 1:04

Use Remastersys. It does exactly what you want and the two times I tried it, I did not bump into any issues
