1547	Nginx trying to create NGX_HTTP_PROXY_TEMP_PATH even when it is overridden via configuration file	ROMB@…		"configuration slice:
{{{
http {
    client_body_temp_path      /var/nginx/client_body_temp;
    proxy_temp_path            /var/nginx/proxy_temp;
    fastcgi_temp_path          /var/nginx/fastcgi_temp;
    uwsgi_temp_path            /var/nginx/uwsgi_temp;
    scgi_temp_path             /var/nginx/scgi_temp;
}
}}}

strace log:

{{{

close(4)                                = 0

}}}

So, as you can see according to config and strace, all temp paths already exists and overridden from defaults, but for some unknown reason nginx still trying to create /opt/nginx/proxy_temp"	defect	closed	minor		other	1.12.x	invalid			Linux 25cc833843bc 4.9.49-moby #1 SMP Wed Sep 27 00:36:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.12.2
