NAME
rump_tmpfs —
mount a tmpfs fictional fs
with a userspace server
SYNOPSIS
file-system PUFFS
pseudo-device putter
rump_tmpfs |
[options] tmpfs
mountpoint |
DESCRIPTION
NOTE! This manual page describes features specific to the
rump(3) file server. Please see
mount_tmpfs(8) for a full
description of the available command line options.
The
rump_tmpfs utility can be used to mount tmpfs file
systems. It uses
rump(3) and
p2k(3) to facilitate running the
file system as a server in userspace. As opposed to
mount_tmpfs(8),
rump_tmpfs does not use file system code within the kernel
and therefore does not require kernel support except
puffs(4). Apart from a minor
speed penalty there is no downside with respect to in-kernel code.
To use
rump_tmpfs via
mount(8), the flags
-o rump and
-t
tmpfs should be given. Similarly,
rump_tmpfs is used instead of
mount_tmpfs(8) if
“rump” is added to the options field of
fstab(5).
