Right, by my point was more that this sysctl value will be set in a default Debian installation by virtue of Recommends being installed by default. For this reason, I think it would be reasonable to consider either installing it (and applying its settings) directly in autopkgtest and/or the debci infrastructure, or simply setting the sysctl directly. Because the linux-sysctl-defaults package currently does not actually take any steps to apply the provided sysctl values, simply installing the additional package won't actually help. Packages can use sysctl from procps and use that, but easiest way to deal with this on a per-package basis probably is to have the test declare 'needs-sudo' and run: echo "0 1073741823" | sudo tee /proc/sys/net/ipv4/ping_group_range from the test script. That feels like a bit arcane of a thing to require random packages to do just to be able to invoke ping in their tests. noah
