Ah, Ubuntu _Server_. I'm tempted to dismiss this by simply saying "Server Linux != Desktop Linux", but yeah, I don't like that this is on by default either. I mean, this is a setup that ships with a default password that's the same as the username, and the first thing I do on all my server installs is disable all default user accounts and enable passwordless sudo. From reading other docs of Ubuntu Server, it appears they relax the root/non-root distinction in other ways too. But I'd probably never have suspected this particular vector of vulnerability.
