Well, mail works now, as does web and even the cute little weblog script, but logging on an X session at the console fails pretty heinously. (Specifically, rxvt fails complaining that it couldn't open the pseudo-tty, or could not obtain control of tty, depending on what random bit I flipped before I tried to launch it.) Plain old xterm seems to work just fine, though. More debugging later, I guess. For now, I'm just going to go to sleep.
