3 ramfs \- memory file system
19 starts a process that mounts itself (see
27 process implements a file tree rooted at
29 keeping all files in memory.
30 Initially the file tree is empty.
34 option enables a trace of general debugging messages.
40 to use file descriptors 0 and 1 for its communication channel
41 rather than create a pipe.
42 This makes it possible to use
44 as a file server on a remote machine: the file descriptors 0
45 and 1 will be the network channel from
47 to the client machine.
53 to make its memory `private'
56 so that its files are not accessible through the debugging interface.
63 to post its channel on
65 .RB ( /srv/ \fIsrvname\fR)
66 rather than mounting it on
68 enabling multiple clients to access its files.
69 However, it does not authenticate its clients and its
70 implementation of groups is simplistic, so
71 it should not be used for precious data.
77 to consume as much memory as needed;
80 will limit its consumption to some arbitrary amount,
81 currently 768MB (enough to hold a CD image).
83 This program is useful mainly as an example of how
84 to write a user-level file server.
85 It can also be used to provide high-performance temporary files.
