With ifconfig_gif0_ipv6 set to include NOAUTO before a restart of the operating
system, the interface was unexpectedly up following a restart.
Relevant lines from the attached screen recording:
% grep ifconfig_wlan0 /etc/rc.conf
ifconfig_wlan0="WPA SYNCDHCP NOAUTO"
% grep ifconfig_gif /etc/rc.conf | grep -v \# | cut -c 1-26,66-100
ifconfig_gif0_ipv6="inet6 prefixlen 128 NOAUTO"
