We stumbled across this distribution the other day while building a forensic workstation for the lab. SIFT just didn’t perform the way we wanted and DEFT seems to be rock solid out of the box with version 7 of their distro.
Check them out at http://www.deftlinux.net/2012/01/31/deft-7-ready-for-download/
They have a draft version of their english manual as well. This distro is based on the 3.0 kernel and is snappy as heck even on somewhat older hardware. Outstanding work guys!
