Linux Mint Debian Edition (LMDE) is the branch of Linux Mint that is based on Debian, unlike Linux Mint editions which are based on Ubuntu Desktop. But how can you tell which Mint release is based on Debian and which one is based on Ubuntu? Here’s the answer from the FAQ section of the release notes:
Frozen releases are based on Ubuntu. They carry a version number. For instance, Linux Mint 10 is based on Ubuntu 10.10. The next frozen release will be Linux Mint 11, based on Ubuntu 11.04.
Rolling editions do not carry version numbers. They follow the Debian Testing branch. Because of their rolling nature, they’re receiving continuous updates and their version number never changes (technically it’s always “1″ though we do not mention it since it’s not relevant). Note the absence of version number in “Linux Mint Xfce” for instance, indicating its rolling nature.
An important thing to notice is the fact that rolling editions are in constant evolution but that a particular ISO image is a snapshot of this edition at a particular time. So, though rolling editions do not get outdated, ISO images do. For this reason we use a timestamp for our ISO images, such as “Linux Mint Xfce (201104)”.
LMDE Xfce is the second Debian-based edition to be released. The first (see Linux Mint Debian Edition review) is powered by the GNOME desktop environment. This article presents a detailed review of LMDE Xfce.
