I noticed a BUG in the solution descriped at FAQ 7.3. As I edited my /etc/gettyttab (like it was descriped in the FAQ) and loged in using ttypC2 I noticed that the the the buffer wont be deleted if you do the followring.
Login at e.g. ttyC2, Do something to get a full screen (so that you need page-up for scrolling) - e.g. some "ls" (7x ls in my case) logout using ctrl-d You can STILL scroll up and see what was entered at this console. I would say that's a "bug" because the buffer should be cleaned after I logged out. I found out that the buffer will be deleted if I switch to another console and back to ttyC2. I tested that on amd64 and i386 and I saw the same effects at both archs. The FAQ dosn't mentioned that so I guess it's a bug but feel free to advice me. Kind regards, Sebastian
