I don't support increasing the default timeout. That would cause problems for a lot of server systems that rely on the relatively short two hour default. The best I think you could do would be to increase it to something like 12-24 hours as a default, but even that might be problematical. Actually, I think we should leave it alone. I don't mind if people add an rc.conf variable, however. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
