:Not that this is crucially important, but does nfsd really need to
:hold open 4 filehandles? I can understand the one on it's binary, but
:according to lsof, it holds open 3 copies of /dev/null (for stdin,
:stdout and stderr).

:|David Gilbert, Velocet Communications. | Two things can only be |
nfsd probably doesn't, but its a general safety feature when it
daemonizes to prevent standard open()'s from using descriptors 0, 1,
and 2. Don't worry, the file handles are simply 3 references to
the same device and should not be taking up any space in the file table.
