.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility can be used to mount lfs 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_lfs 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_lfs 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_lfs 8
|
|
for a full description of the available command line options.

.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.
