.Sh NAME
|
||||
.Nm rump_nfs
|

.Nd mount the nfs file system using a userspace server

|

.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility can be used to mount nfs file systems.
|
||||
It uses
|
||||
.Xr rump 3
|
||||
and
|
||||
.Xr p2k 3
|
||||
to facilitate running the file system as a server in userspace.
|
||||
As opposed to
|
||||
.Xr mount_nfs 8 ,
|
||||
.Nm
|
||||
does not use file system code within the kernel and therefore does
|
||||
not require kernel support except
|
||||
.Xr puffs 4 .
|
||||
Apart from a minor speed penalty (~10%), there is no difference to
|
||||
using the in-kernel code.
|
||||
.Pp
|
||||
It is recommended that untrusted file system images be mounted with
|
||||
.Nm
|
||||
instead of
|
||||
.Xr mount_nfs 8 .
|
||||
Corrupt file system images commonly cause the file system
|
||||
to crash the entire kernel, but with
|
||||
.Nm
|
||||
only the userspace server process will dump core.
|
||||
.Pp
|
||||
Please see
|
||||
.Xr mount_nfs 8
|
||||
for a full description of the available command line options.

||||

|
||||
.Xr p2k 3 ,
|
||||
.Xr puffs 3 ,
|
||||
.Xr rump 3 ,
|
||||
.Xr mount_nfs 8
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
utility first appeared in
|
||||
.Nx 5.0 .
|
||||
.Sh BUGS
|
||||
.Nm
|
||||
cannot be used via
|
||||
.Xr mount 8 .
|
||||
Instead,
|
||||
.Nm
|
||||
must be run directly.
