This may be a stupid question, but I haven't shied away from asking stupid questions before... Do we have to consider this as an "on/off" switch? Could we have it an "on/off/extended" switch? (or is the value stored as a bit somewhere, so that it can only be on or off?). What I'm thinking is that anything that explicitly asks for "on" would get the current 2-hour timeout, but that the "extended" setting would result in a 7-day timeout. We'd then set the system default to "extended" instead of either on or off. Or would this break things in subtle ways? --- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or drosih@rpi.edu Rensselaer Polytechnic Institute To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
