Using tmux properly
<i>I use ... Screen on production servers. ... Screen has the lightest footprint</i><p>dtach, which is what I use on production servers even though it usually doesn't come standard, probably has the lightest footprint if you just want to return to some screen later. It doesn't maintain history, however, the screen is redrawn, if possible, on reattach.<p>Otherwise, yes. Both tmux and the book are great (if you don't mind getting drawn into wasting time on customizing the status bar and such).
