Hmm, so we actually apply sysctls very early in the boot, and we do not
spawn normal services before this finished. There's one exception
however: settings on network interfaces are applied as the network
interfaces show up, but before the udev event for them showing up is
send to the applications. That means that any app running in the normal
start-up phase and/or using udev to listen for network interfaces
showing up should see sysctls only fully applied.
There must be something else going wrong here?
