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

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

SYNOPSIS
     file-system PUFFS

     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.
