There was one noticeable change in the nginx packages recently.
Before nginx 1.9.8 we shipped nginx-debug binary (that is nginx
configured and compiled with —with-debug option, needed for
debugging: http://nginx.org/en/docs/debugging_log.html) in
the separate package “nginx-debug”. Since 1.9.8 this binary
was moved to the main package. Now it is possible to start
nginx-debug binary with the init-script:
% service nginx stop
% service nginx-debug start
nginx-debug will use same config files.
