RUMP_TMPFS(8)

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).
