Not sure how this slipped by us, but it only seems appropriate after covering the Mac release of limera1n; Greenpois0n was updated 2 days ago to include a version available for Linux. While the Mac version is yet to be available, you can use Limera1n in the meantime, which has recently been released for Mac OS X.
The chronic dev team has said that the Mac version is almost near completion, as they work out a few small issues. Once that comes out, Greepois0n will be compatible on a total of 3 operating systems. It is unknown if GeoHot has plans for a Linux Limera1n.
