Title:
  nm-online returns too early

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  
  I am setting up a totem system which mounts a remote file system at boot and starts an application from it.

  I found that randomly the boot fails because the mount fails due to
  "Network unreachable" errors.

  I made sure the mount unit waits for network-online.target to be
  rached, however I found that NetworkManager-wait-online.service
  returns well before the IP address has been obtained by DHCP.

  This is a cleaned up log extract:
