Found while trying to figure out how to be sure the console is always cleared at logout (and the resulting login prompt seemed like a pretty guaranteed-to-always-work place). If you have a cleaner way, perhaps one that is actually at logout and doesn't involve missing all the startup messages due to clearing right after them (and is just as reliable, and preferably just requires changing config files, not source), then by all means, please let me know.
For now I've just added cl=\033[2J\033[;H to my gettytab's default entry, and it does more or less what I want. For the archives: I'm doing this in conjuction with ksh's TMOUT option. See ksh(1). Also note that I'm doing this for consoles (Ctrl+Meta+<number>) (not X11) which I find myself frequently forgetting I am logged into when I suspend my laptop (which auto-locks X, among other things).
