I have configured OMV 4 to force SSL usage and I'm running Baikal for syncing calendars to some Android 4.2/4.4 smartphones. Those old Android versions don't work with the default ssl_ciphers, so I have to add additional ones to /etc/nginx/openmediavault-webgui.d/security.conf.
In addition to this I'm running some PHP services and I have setup the paths and usage as described there. To make this working another include directive has to be added to /usr/share/openmediavault/mkconf/nginx.d/10webgui.
With every update, my manual additions are being deleted, so I'd like to know if there is any way to customize Nginx to allow such customization?
