s3fs

These may not be useful to anyone else, but who knows.

If you're getting the error "s3fs: could not determine how to establish security credentials", make sure the password file is named passwd-s3fs, and not password-s3fs.

If you're getting the error "s3fs: unable to access MOUNTPOINT No such file or directory", try setting the mountpoint directory to 777.

These are what solved my problems today, at least!
