I was able to install Ubuntu on a mini pc and to configure everything I needed, I lost a lot of time configuring stuff and recompiling part of the kernel following different tutorials on internet. I have also customized unity, now I don't want to loose the same time next time.
Is there a way to create a distribution from what is now in my HDD and be sure that if I install this distro next time on the same machine,or another, starting from scratch, everything will be exactly how it is now?
(I don't want to create a disk image.)
