| 2 | .SH NAME |
| 3 | ramfs \- memory file system |
| 4 | .SH SYNOPSIS |
| 5 | .B ramfs |
| 6 | [ |
| 7 | .B -i |
| 8 | ] |
| 9 | [ |
| 10 | .B -S |
| 11 | .I service |
| 12 | ] |
| 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 | .IR 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. |
