We may want to look at decoupling FUSE from S3 initialization which may allow returning the correct error code when -f is not specified.

@gaul Is there an issue tracking this idea? This is what I want to achieve ideally.

Brief description:
I'm calling s3fs-fuse programmatically from another language (Go) using the execve pattern (and from Bash scripts, actually). I would like to be able to know when something went wrong by checking the exit code of the execve'd process (and to be able to discern meaning from the code).

The ideal scenario would be to also be able to get errors from FUSE and also for s3fs-fuse to block until the filesystem is mounted or an error forces it to exit. (The parent is wait-ing for it to exit.)

Am I thinking at this backwards? Should I be using some Go wrapper for s3fs-fuse (if such thing exists)?
