I'm curious about why the sysctl settings I quoted are considered best practices in cloud environments, and not in other environments (including standard server environments)? I'm not against having a discussion about Debian providing different kernel settings profiles for different environments. This is something that could probably be useful (those settings can be configured for a reason, after all). However, I don't think that this is something that should be decided silently by the cloud team on its own, but rather discussed with the kernel team to find a solution that works for everybody. Lucas
