Advanced users of GNU/Linux (and I mean advanced), remember to try Source Mage GNU/Linux. True source-based distribution, and (in contrast with Gentoo and Arch) is: Free from obfuscated and pre-configured code. Fully committed to GPL, uses only free software (as in freedom) in their main package. With even the documentation licensed as FDL. Without 3rd party patches, sensible defaults or masked packages. Doesn't need obfuscated python libraries, only bash. No systemd (they've implemented their own init scripts system http://sourcemage.org/Init). Uses clean dependencies as they came from upstream developers, which by the same provides instant updates. Can heal broken installs. Can also use flags.
Do you like Arch Linux's AUR? Do you like Gentoo's portage (or ports-like) package manager? With SMGL's "sorcery" you get all that. Making new spells (package build files) not found in the grimoire (repository of spells) is easy http://sourcemage.org/Spell/Book
