Example of a vfstab entry

You want a client computer to mount the /var/mail directory on the server wasp. You would like it mounted as /var/mail on the client. You want the client to have read-write access. Add the following entry to the client's vfstab file.

wasp:/var/mail - /var/mail nfs - yes rw

NFS servers should not have NFS vfstab entries because of a potential deadlock. The NFS service is started after the entries in /etc/vfstab are checked, so that if you have two servers fail at the same time that are mounting file systems from each other, each system could hang as the systems reboot.
