By googling the error message I found a thread where somebody has the
same question, but I wouldn't recommend following the advice there
(running the yocto build as root). How do you extract the root
filesystem to your NFS directory? Maybe something is wrong there and
the files get extracted with UID 1000 as owner. For reference, I use
this command which seems to work fine:

sudo tar --strip-components=1 -C /srv/nfs/rootfs -xf images/apalis-
imx6-mainline/Apalis-iMX6-Mainline_Image.rootfs.tar.xz

Also check that there are no setuid/setgid bits set.

I'm using pretty much the same NFS options, the only difference I could
spot is an additional 'fsid=root' in my exports which is NFSv4
specific.
