Example of a vfstab entry

You want a client computer to mount the /var/mail directory from the server wasp. You would like the file system to be mounted as /var/mail on the client and 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 two servers that are mounting file systems from each other fail at the same time, each system could hang as the systems reboot.
