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).
