This is a follow-on to I475a253091cbaf63687b91c748c31a6753bb0f57 as we are still seeing issues on some clouds with unconfigured networking. We increase the timeout, but also make it configurable so we can fiddle it without a dib release in the gate. To follow-on from the experimentation done by clarkb, I can confirm by emperical testing on a Centos 7 image (from today, today being this change's date) that setting net.ipv6.conf.all.autoconf=0 by itself is "fatal" and the interfaces do not come up; i.e. nm does not by default seem to re-enable ipv6 for the interface. However, explicitly adding: IPV6INIT=yes IPV6_AUTOCONF=yes to the interface file *does* seem to make it work, even if "all.autoconf=0" is set (then again, there's also bugs about the effect of this [1]). However, no extant distribution (I can currently find) does anything like this by default. If this continues, this may be an option. Another might be to avoid the use of the nm-settings-ifcfg-rh profiles and move directly to nm ini files with glean.
