[proc/sys/usb/udev/devpts pseudo-fses]

rpc_pipefs is used by NFS clients and servers. However, on a relatively
normal NFS client here, the only thing that's using that pseudo-fs is
rpc.idmapd, which is useful in some cases but probably not relevant.

The binfmt_misc pseudo-fs is there for OS execution of miscellaneous binaries.
For example, you could associate .exe files with wine, and just run those
with "solitaire.exe" instead of "wine solitaire.exe". It's controlled by the
binfmt_misc kernel module, and probably has a config file somewhere.

A few days ago, I asked for the output from "ps auxw | grep nfs" and "dmesg |
grep -i nfs". Find out what (if anything) is running on this machine that's
related to NFS. Also, do "dmesg | more" and eyeball-grep the results for
anything weird-looking.
