RUMP_SYSPUFFS(8)		   BSD System Manager's Manual			 RUMP_SYSPUFFS(8)

NAME
     rump_syspuffs -- mount a puffs file server with a userspace puffs loop

SYNOPSIS
     file-system PUFFS
     pseudo-device putter

     rump_syspuffs file_server arguments

DESCRIPTION
     The rump_syspuffs utility can be used to mount any 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.

     In its current state, rump_syspuffs is most useful as a proof of concept for file system
     distribution and for developing and debugging the kernel portion of puffs.

EXAMPLES
     Mount a file system with sshfs:
	   rump_syspuffs mount_psshfs server.address /mnt

     Mount an ntfs file system using ntfs-3g (from pkgsrc/filesystems/fuse-ntfs-3g), set the
     default uid to 1323:
	   rump_syspuffs ntfs-3g -o uid=1323 /path/to/filesystem /mnt

SEE ALSO
     p2k(3), puffs(3), rump(3), puffs(4)

HISTORY
     The rump_syspuffs debugging utility first appeared in NetBSD 5.0.
