We didn’t take such survey. I think because Badblock was an upstream bug. We had an announcement on this forum and there we followed all the story.
Luckily, problems like this occurs rarely. This is the reason because NethServer updates are manual: the admin is responsible for them.
As suggested on the thread, I didn’t applied the upstream update to my customers until RedHat fixed their RPMs. Maybe the release of CentOS 6.8 slowed down the fix release and we had to wait more weeks for that.
