I'll try this and report back. Do you think I should add a new command-line option to pass the interface to ConnMan? Identifying the interface used for NFS requires parsing /proc/cmdline and, in case of static addresses, knowledge about the interfaces' IP address. Until now I preferred to let the shell do it.
