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).
The rump_tmpfs
utility first appeared in
NetBSD 5.0.
