I have planned to make a customized "Kubuntu" 14.04 LiveCD. For that, I tried using Ubuntu Customization Kit. Several attempts were made and built many custom kubuntu iso files but none of them were in a working state. Process to make the custom iso was successful and no errors occured in build process and also, the writing of iso was performed correctly to USB.
When booted with USB, I couldn't use it as a LiveUSB. So to track the actual fault, I installed it directly to Hard Drive. However it installed. But I couldn't login into the administrator account after installing that custom iso in my system. Only Guest was allowed to be accessed.
All the iso's created showed the same behaviour of being stuck, and hence I reinstalled back the Kubuntu again, that was available in the official website.
When searched in the internet, I came to know that custom KDE(kubuntu) iso made with Ubuntu Customization Kit will have some glitches, as UCK was excellent in handling GNOME, LXDE whereas it is not good in handling KDE.
Then googled out for other alternatives. I found Remastersys, Relinux, and Ubuntu Builder. Remastersys is discontinued and supports making custom LiveCD's upto Saucy Salamander. Ubuntu Builder is also a discontinued project. I cannot create custom iso using Relinux as it simply loops indefinitely i.e from start to end of config and goes back to starting of config.
Reason for creation of Custom ISO:
I needed a backup of installed programs Cheese, GIMP, VLC, g++, build-essential, synaptic, XAMPP(installed manually from ApacheFriends) so that whenever I need a reinstallation, if installed with custom iso, I need not install again and again.

P.S. Is there any special software for KDE for making custom iso?
