13 .SH DESCRIPTION
14 .I Ramfs
15 starts a 9P file server 
16 keeping all files in memory.
17 Initially the file tree is empty.
18 .PP
19 By default
20 .I ramfs
21 posts its service as
22 .B ramfs
23 using
24 .MR 9pserve (4) .
25 .PP
26 The
27 .B -S
28 flag specifies an alternate service name for ramfs to use.
29 .PP
30 The
31 .B -i
32 flag tells
33 .I ramfs
34 to use file descriptors 0 and 1 for its communication channel
35 rather than create a pipe.
36 This makes it possible to use
37 .I ramfs
38 as a file server on a remote machine: the file descriptors 0
39 and 1 will be the network channel from
40 .I ramfs
41 to the client machine.
42 .PP
43 This program is useful mainly as an example of how
44 to write a user-level file server.
45 It can also be used to provide high-performance temporary files.
