NAME
       ramfs  - memory file system

SYNOPSIS
       ramfs [ -i ] [ -s ] -m [ mountpoint ]

DESCRIPTION
       Ramfs  starts  a process that mounts itself (see bind(2)) on mountpoint (default /tmp).	The ramfs process implements a file tree rooted at
       dir, keeping all files in memory.  Initially the file tree is empty.

       The -i flag tells ramfs to use file descriptors 0 and 1 for its communication channel rather than create a pipe.  This makes it possible to
       use  ramfs as a file server on a remote machine: the file descriptors 0 and 1 will be the network channel from ramfs to the client machine.
       The -s flag causes ramfs to post its channel on /srv/ramfs rather than mounting it on mountpoint, enabling multiple clients to  access  its
       files.  However, it does not authenticate its clients and its implementation of groups is simplistic, so it should not be used for precious
       data.

       This program is useful mainly as an example of how to write a user-level file server.  It can also be used to provide high-performance tem-
       porary files.
