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.
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
The rump_syspuffs
debugging utility first
appeared in NetBSD 5.0.
