NFS not working on Jessie Tinkerboard build

I build a kernel last night because I wanted a headless debian based system, not the nightly desktop available for download.

Everything went well (almost*) until I tried installing NFS

A little googling leads me to believe dnotify is not enabled in the kernel... which was supposed to be replaced by inotify many years ago.

Is this simply a config option in the kernel? If it is, can someone point me towards the way I go about enabling this? I've been building in the recommended Ubuntu 16.04 VM

* almost... eth0 doesn't get an IPv4 address anymore since it's first boot. manually running dhclient after boot from the console works.
