RUMP_TMPFS(8) | System Manager's Manual | 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).
