RAMFS(4) RAMFS(4)
NAME
ramfs - memory file system
SYNOPSIS
ramfs [ -abcAD ] [ -s srv ] [ -m mnt ] [ -n addr ] [ -V
volspec ]
DESCRIPTION
Ramfs services a ram file system for temporary and volatile
files. By default, ramfs mounts itself at /tmp. Option -m
can be used to mount it at mnt instead. Flags -abc mount
after, before, and allowing file creation, as mount(2)
describes.
In the same way, options -s and -n request the server to
register srv with srv(3) and to listen for clients at net-
work address addr. Clients are authenticated via factotum(4)
unless flag -A is given or the client connects from the
local machine.
This program is useful as a volatile place holder of infor-
mation that must be exported to the network in a secure way.
It is a good candidate to place on it synthetized and con-
text information for others to know.
The -V option makes ramfs announce the volume with the given
volspec and appropriate default constraints for the user
name, system name, and location.
The -D flag shows 9P messages sent and received, for diag-
nostics.
In gereral, the options related to Plan B file servers for
volumes are described in planbfs(4) and have the same mean-
ing in this and other file servers developed for Plan B.
