Public bug reported:
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:
