please change EPERM to EACCES before committing this. EPERM is only acceptable for S_ISVTX, not for: "[EACCES]
Search permission is denied on a component of the path prefix, or write permission is denied on the parent directory of the directory to be removed." which is the case here.

Okay - so I finally got ready to do this (after some git wrangling) - and read back through this email - Why are you saying that this needs to be EACCES?


Unless I am misreading the file, this particular branch of execution only affects '/' - and more specifically, the case of trying to 'mkdir(/) or rmdir(/)' - there is a section later (commented 'POSIX junk') that deals with other cases..

And you're saying (or I suppose POSIX is saying, and you're quoting)

"Search permission is denied on a component of the path prefix, or write permission is denied on the parent directory of the directory to be removed."

But there is no parent or prefix of '/' - so I don't see how that is the case here as you suggest. This case is basically saying 'root already exists and cannot be removed', where it was before saying 'you cannot or create or remove root'.

Rather philosophical, really.. maybe I will change the comment.

Anyhow.

please advise / clarify / etc.

Thanks
