Decided to share my fork of remastersys. This is the script used to build Pinguy OS.

The script can create a livecd of the installed system and works with *buntu systems.

You can either make a distributable livecd or a backup of your system.

Notable Changes:

Single package for Script and GUI.

Full EFI support including EFI partition on ISO.

Populate pool folder with grub-efi for offline installing.

Update grub entry with the named used for the CD label.

Uses XZ to compress the filesystem.squashfs for smaller ISO size.

See the version you need from the README from the link.
