For example, consider the `LD_PRELOAD` environment variable that is set in the `systemd` override configuration file. When `NGX_CHANGEBIN_SIGNAL` is set to nginx master process, it does not start the new process with the environment variable `LD_PRELOAD` set. Adding this variable to NGINX configuration via the `env` directive doesn't help, because it properly affects the dynamic linking for the child processes. I believe that the `NGX_CHANGEBIN_SIGNAL` handler should preserve the environment when launching a new master process because if it is not preserved, different shared libraries could silently be loaded after a binary upgrade. Thanks for taking a look.
