Instead, show us the mount command used or the according (if applicable) /etc/fstab line.
I've tried about 50 combinations, in the current and most simple form I use /etc/fstab

Code:
#
# Warning - this file should only be modified with vifs(8)
#
# Failure to do so is unsupported and may be destructive.
#
cady:/volume1/nfs       /System/Volumes/Data/nfs        nfs     rw

But in an attempt to try a lot of different combinations quickly I just used mount commands directly. Here's a sampling from my history.

Code:
mount cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o resvport cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o noacl cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o nolock cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o nfsvers=4 cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o nfsvers=2 cady:/volume1/nfs /System/Volumes/Data/nfs
mount -o rw,sync,no_root_squash,no_subtree_check,insecure cady:/volume1/nfs /System/Volumes/Data/nfs
...
...

Using either mount commands directly, or using auto_master/auto_nfs, or /etc/fstab I can easily get the NFS drive mounted, and the permissions and ownership is correct. From a shell I can copy files to/from the local system to the NFS mount without troubles. The logs on the NFS server show no errors. I've already posted the unhelpful error log from the client machine.

I've tried lots of different combinations of owner/group/permissions via chown, chgrp and chown. Currently sitting at:

Code:
brians-mbp:etc root# ls -la /System/Volumes/Data/nfs/hosts
-rwxrwxrwx 1 1024 _lpoperator 2393 Feb 8 14:29 /System/Volumes/Data/nfs/hosts

I was hoping somebody familiar with how Mac OS X specifically creates the environment in which Launchd or cron jobs run could shed some light. Even though root has access to the files, and the Launchd or cron job is owned by root, it somehow isn't executed with normal root rights.
