NFS (network file system) on Ubuntu 16.04

2020/03/26 Kenlo Nasahara

* Suppose xxx.xxx.xxx.xxx is the IP address of the NFS server.
* Suppose yyy.yyy.yyy.yyy is the IP address of the NFS client.
* Suppose you want to mount /work on the server to /work on the client.
* Note: In some cases, SSH-FS may be more useful and suitable than NFS.NFS. Especially if you are not admin of the server, and the admin does not help you, NFS is a bad choice.
