I strongly disagree. Nginx should be removed. It's bloat. There's no need for a multi-process, web server capable of c10k requiring over 15x the flash space and 37.4x the RAM when OWRT is a single seat administered, embedded system.

There's no benefit to Nginx when it doesn't even have proper WebDAV support.
