1017634 - New spot test images don't have v4l2loopback configured

Status: RESOLVED FIXED

Description

[(not currently active) Ted Mielczarek]

In bug 826265 we got the v4l2loopback driver configured on the Linux test slaves. However, when I landed bug 815002 it showed that we have some slaves that are not properly configured. Rail says they're the new spot images and it has something to do with puppet.

Dropped support for CentOS for now (we don't use this module on other platforms). Worked fine.

it may take some time until all new instances get this change (by EOD for sure)

I think there is a missing notify for the case when we have the packages installed but not added the modules to /etc/modules.

see, https://bugzilla.mozilla.org/show_bug.cgi?id=815002#c55
