Gad, I'm real confused. I can roughly grok the difference between stable, unstable, etc. But what's this business of "2.2r3" and "2.2r4"? How does this relate to the version number "2.2.18pre21". Where does "potato" leave off and "woody" begin? What's with the 2.4.x kernels? Where do they stand in relation to "potato" and "woody?" Is there a FAQ or URL that might help to understand any of this? Thanks! rafe b.
