What we need is a matching "Simple Shutdown Flag" variable. Personally I was not that much thinking about the particular problem at hand. I think the fast boot BIOS preference should be simply exported by the kernel as a sysconf erm. sorry sysctl constant value to allow for easy checking by userland. One could imagine that a lot of other preferences could be controlled by it as well. Like for example starting dhclient dettached from the current console, just to give the user a login prompt as fast as possible and so on... -- Marcin Dalecki To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
