The current code is calling log.Errorf for file system errors. File system errors can be frequent, as in a shell searching $PATH.
These errors will be visible to the NFS client, and the NFS server are very confusing when running shells on NFS-mounted file systems, since the shell will handle the error.
The shell is just one example; searches of LD_LIBRARY_PATH, /usr/include, etc: all produce copiuos error messages that are not needed. The error is returned to the client and can be handled there.
Note that if there is a protocol-level error, such as failure to return a response packet, the error prints will still happen. In that case, it may be appropriate.
Fixes #117.
