.Sh NAME
.Nm rump_syspuffs
.Nd mount a puffs file server with a userspace puffs loop
.Sh SYNOPSIS
.Cd "file-system PUFFS"
.Pp
.Nm
.Ar "file_server"
.Ar arguments
.Sh DESCRIPTION
The
.Nm
utility can be used to mount any
.Xr puffs 3
file server so that the requests are passed through the kernel
puffs code in userspace as well.
Therefore the approximate callgraph looks a little like the following,
where k and u denote code running in the kernel space and userspace,
respectively:
puffs vfs (k) \(-> libpuffs (u) \(-> p2k (u) \(-> puffs vfs (u) \(->
libpuffs (u) \(-> file server (u).
The response path is the same, but in reverse.
.Pp
In its current state,
.Nm
is most useful as a proof of concept for file system distribution
and for developing and debugging the kernel portion of puffs.
.Sh EXAMPLES
Mount a file system with sshfs:
.Dl rump_syspuffs mount_psshfs server.address /mnt
.Pp
Mount an ntfs file system using ntfs-3g (from pkgsrc/filesystems/fuse-ntfs-3g),
set the default uid to 1323:
.Dl rump_syspuffs ntfs-3g -o uid=1323 /path/to/filesystem /mnt
.Sh SEE ALSO
.Xr p2k 3 ,
.Xr puffs 3 ,
.Xr rump 3
.Xr puffs 4
.Sh HISTORY
The
.Nm
debugging utility first appeared in
.Nx 5.0 .
