AutoFS
It may be preferable to mount NFS shares on demand, instead of at boot in /etc/fstab as seen in the guides above.

Security
NFS by default does not require a password to connect.

In addition, if you are root you will be able to bypass all POSIX permissions on the files. Special security setups will be necessary to prevent this, which may include SSO.
