Re: [PATCH v3 02/10] unix-sockets: use strbuf_getcwd()

> Instead of using a PATH_MAX-sized buffer, which can be too small on some
> file systems, use strbuf_getcwd(), which handles any path getcwd()
> returns.  Also preserve the errno set by strbuf_getcwd() instead of
> setting it to ENAMETOOLONG; that way a more appropriate error message
> can be shown based on the actual reason for failing.
