Package: nginx In order to provide a simpler way to handle virtual hosts and site-specific configuration, the nginx package for the Debian system will use the sites-available/ and sites-enabled/ directories starting from 0.5.18-1 (about to be uploaded to Sid) If you haven't configured nginx to your exact needs, it's safe to overwrite the old configuration with the new one, since it's backwards compatible. However, note that dpkg will respect your current configuration file by default, though it will create the sites-available/ and sites-enabled/ directories with the default configuration. You can migrate to the newer configuration handling model at any time just by moving your server directives to sites-available/ and making a symbolic link to it in sites-enabled/ Users from the Debian GNU/Linux 4.0 (Etch) distribution should not take any specific actions now, since the packages shipped in 4.0 will use the old single-configuration-file approach. Please report any bugs or problems, and thank you for your interest in nginx and Debian, Jose
