MintPup-Trusty is a fork of DebianDog based on Linux Mint 17.1 and Ubuntu-Trusty
The project started by wanderer in this thread.
MintPup is small 32-bit Ubuntu/Mint based live CD shaped to look and act like Puppy Linux. Ubuntu structure and Ubuntu behaviour are untouched and Ubuntu/Mint documentation is valid for MintPup. You have access to all Ubuntu/Mint repositories using apt-get or synaptic.
