Hi, It seems that the Debian EC2 images ship with non-default sysctl tunings. Apparently, those are generated by https://github.com/andsens/bootstrap-vz/pull/256/commits/06da309895f69573996a4c1ff027f999155b876b
I noticed because #830353, #830452 and #831249 are triggered by this. One could argue that those test suites are a bit fragile, but on the other hand, I would expect an image labelled as "Official Debian" on https://wiki.debian.org/Cloud/AmazonEC2Image to not differ from default Debian configuration in subtle ways like this. Also, I did not find where to report such issues (I looked at https://wiki.debian.org/Cloud/AmazonEC2Image and https://wiki.debian.org/Cloud/AmazonEC2Image/Jessie). It seems that the only bug tracker is on github. That also surprises me for "Official Debian" images. Thanks, Lucas
