.Sh NAME
.Nm rump_xxxfsxxx
.Nd mount a xxxfsxxx xxxfssrcxxx with a userspace server
.Sh SYNOPSIS
.Cd "file-system PUFFS"
.Cd "pseudo-device putter"
.Pp
.Nm
.Op options
.Ar xxximagexxx
.Ar mountpoint
.Sh DESCRIPTION
.Em NOTE!
This manual page describes features specific to the
.Xr rump 3
file server.
Please see
.Xr mount_xxxfsxxx 8
for a full description of the available command line options.
.Pp
The
.Nm
utility can be used to mount xxxfsxxx 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_xxxfsxxx 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 there is no downside with respect to
in-kernel code.'

MANTMPL_BLK='.Pp
.Nm
does not require using
.Xr vnconfig 8
for mounts from regular files and the file path can be passed
directly as the
.Ar xxximagexxx
parameter.
In fact, the use of
.Xr vnconfig 8
is discouraged, since it is unable to properly deal with images on
sparse files.
.Pp
In case the image contains multiple partitions, the desired partition
must be indicated by appending the token
.Dq %DISKLABEL:p%
to the
.Ar xxximagexxx
path.
The letter
.Dq p
specifies the partition as obtained via
.Xr disklabel 8 .
For example, to mount partition
.Dq e
from image
.Pa /tmp/wd0.img ,
use
.Dq /tmp/wd0.img%DISKLABEL:e% .
.Pp
It is recommended that untrusted file system images be mounted with
.Nm
instead of
.Xr mount_xxxfsxxx 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.'

MANTMPL_NET='.Pp
Even though the
.Nm
file system client runs within a virtual rump kernel in userspace,
it uses host network services
.Pq by means of Dq rump sockin .
This means that regardless of whether using
.Nm
or
.Xr mount_xxxfsxxx 8 ,
the same network configurations will be used.
Currently,
.Dq sockin
supports IPv4.'

MANTMPL2='.Pp
To use
.Nm
via
.Xr mount 8 ,
the flags
.Fl o Ar rump
and
.Fl t Ar xxxfsxxx
should be given.
Similarly,
.Nm
is used instead of
.Xr mount_xxxfsxxx 8
if
.Dq rump
is added to the options field of
.Xr fstab 5 .
.Sh SEE ALSO
.Xr p2k 3 ,
.Xr puffs 3 ,
.Xr rump 3 ,
.Xr mount_xxxfsxxx 8
.Sh HISTORY
The
.Nm
utility first appeared in
.Nx xxxfirstxxx .'
