[yocto] Small problem on systemd unit files provided by nfs-utils recipe

[Pedro Pozzobon]

Hello,

While I was trying to use the NFS server provided by the nfs-utils.bb
recipe I've noticed an unexpected behavior when
trying to start the systemd service using 'systemctl start
nfs-server.service': when I first call this
command nfs-server fails to load and I need to call it a second time to
make it work properly.

After noticing this, I tried to compare these .service files with the ones
provide by other distros and tried to make some changes on it but I
wasn't successful.

I know this is not a big problem, but making two calls for 'systemctl
start' seems not to be the ideal behavior and I'd like to fix this. Does
anyone know
how to make it work properly? I'm currently using the recipe provided by
Krogoth 2.1.1.

Some information:

After a reboot and using 'systemctl start nfs-server.service', I get the
following messages using 'journalctl -e':
