# NAME

`rump_nfs` —
mount a nfs share with a userspace server

# SYNOPSIS

`file-system PUFFS`
`pseudo-device putter`

`rump_nfs` | [options] share mountpoint

# DESCRIPTION

NOTE! This manual page describes features specific to the rump(3) file server. Please see mount_nfs(8) for a full description of the available command line options.

The `rump_nfs` utility can be used to mount nfs file systems. It uses rump(3) and p2k(3) to facilitate running the file system as a server in userspace. As opposed to mount_nfs(8), `rump_nfs` 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.

Even though the `rump_nfs` file system client runs within a virtual rump kernel in userspace, it uses host network services (by means of “rump sockin”). This means that regardless of whether using `rump_nfs` or mount_nfs(8), the same network configurations will be used. Currently, “sockin” supports IPv4.

To use `rump_nfs` via mount(8), the flags `-o` rump and `-t` nfs should be given. Similarly, `rump_nfs` is used instead of mount_nfs(8) if “rump” is added to the options field of fstab(5).
