Current Behavior

At

We are symlinking our local themes on top of the installed themes by piwigo.

IIUC, the root idea is that we can drag along custom installed themes. This is fine but, unfortunately, piwigo also stores other content, including the "default" theme, in that folder which receives updates from version to version:
https://github.com/Piwigo/Piwigo/tree/master/themes

If we symlink without having this into account, we end having the content of our older piwigo installation still in "themes" after an upgrade.
