> Currently, when using the DF class to determine the mount corresponding to a 
> given directory, it will throw the generic exception "Expecting a line not 
> the end of stream" if it can't determine the mount (for example if the 
> directory doesn't exist).
> This error message should be improved in several ways:
> # If the dir to check doesn't exist, we can see that before even execing df, 
> and throw a better exception (or behave better by chopping path components 
> until it exists)
> # Rather than parsing the lines out of df's stdout, collect the whole output, 
> and then parse. So, if df returns a non-zero exit code, we can avoid trying 
> to parse the empty result
> # If there's a success exit code, and we still can't parse it (eg 
> incompatible OS), we should include the unparseable line in the exception 
> message.
