I am looking for comments on GOOD and RECENT or CURRENT books for Debian, since thats the underlying distro for Knoppix, for a convert.

I've got a background in stuff from a PDP8e to DOS to wimpdoze, and some of the basics of *nix/Linux systems.

I've looked at the offerings at Amazon and various Linux sites and all seem to be several years old. Some 4+ years!

Any thing more current than 2 or more years old.
