nginx 1.9.6 /etc/nginx/html

[basti]

Hello,
I have installed nginx 1.9.6 on debian jessie.
As I can see there is no sites-enabled and sites-available anymore. Is
that right?

An other strange thing is that nginx looks in "/etc/nginx/html" for
files but this dirctory does not exist. For example:

2015/11/24 14:24:51 [error] 14763#14763: *70 open()
"/etc/nginx/html/robots.txt" failed (2: No such file or directory)

But I can't find an entry for "/etc/nginx/html" in any config file
placed in /etc/nginx.
Is it "hard-coded" in source?

Regards,
Basti
