Public bug reported: I'm seeing an empty dhcp lease file. Digging through the code we are passing the -1 opt to dhclient in cloudinit.net.dhcp.dhcp_discovery. This would allow a non-zero return code if dhclient has an issue.
I see though that there is an exit hook for dhclient: https://git.launchpad.net/cloud-init/tree/tools/hook-dhclient. It seems as though this hook could be hiding a non-zero return code from dhclient main lease implementation (unless $reason is in one of those options _and_ `cloud-init dhclient-hook` fails). This does not seem like the desired behavior, as we get beyond the dhclient call then only to fail on a zero-byte dhcp lease file. ** Affects: cloud-init Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
