The system hangs until dhclient times out (or I press ctrl-C on the console :-), then proceeds with normal startup. >How-To-Repeat: Boot a machine configured for DHCP with the network cable unplugged. >Fix: I will attach a patch to the PR once it is issued. A brief synopsis of the patch is: In /etc/rc.network, there is a loop where it goes through all configured interfaces, looking for those set for DHCP. When it finds one, it adds it to the dhcp_interfaces variable. The patch first checks if there is carrier present on the interface, and if not, doesn't add it to dhcp_interfaces. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
