This will hard-wait for 10 seconds even if all devices are ready to roll much earlier than that. An alternative is to set kern.mountroot.timeout which will keep trying the available root devices until the timeout expires and then drop you to the prompt, with the benefit of only waiting 4 seconds if that's how long it really took the device to become ready. (The default for kern.mountroot.timeout is 3 seconds.) -- Ian _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
