Ideally, it would be build progs without utmp(x), and disable build of anything that's a stub after that. For example: uptime would either drop the '<n> users' field, or change it to '?? users' (the latter would keep the right number of fields). wall would disappear, since it enumerates active ttys based on utmp. last would disappear, since it gets login records from utmp(x). > Actually I thought the next step could be to remove utmp and use utmpx > only because it's POSIX and more portable. See commit d00c10ed. That doesn't address what I'm concerned about, though it's a nice thought. (In fact, OpenBSD is utmp only.) I'm saying that it would be *nice* to be able to turn off *everything* that relies on utmp or utmpx, all at once. Is that, at least in theory, acceptable?
