You are perfectly right. Indeed, I’ve discovered that at precompiling assets time, among many other things, the following symlinks are created under the public/plugins folders:
/var/www/discourse$ ls -al public/plugins/
...
lrwxrwxrwx. 1 discourse root 52 Jul 2 09:17 discourse-calendar -> /var/www/discourse/plugins/discourse-calendar/public
lrwxrwxrwx. 1 discourse root 52 Jul 2 09:17 discourse-graphviz -> /var/www/discourse/plugins/discourse-graphviz/public
lrwxrwxrwx. 1 discourse root 48 Jul 2 09:17 discourse-math -> /var/www/discourse/plugins/discourse-math/public
lrwxrwxrwx. 1 discourse root 57 Jun 21 00:28 discourse-narrative-bot -> /var/www/discourse/plugins/discourse-narrative-bot/public
lrwxrwxrwx. 1 discourse root 44 Jun 21 00:28 styleguide -> /var/www/discourse/plugins/styleguide/public
That was not the case for our infrastructure.
Thank you, so no bug at all, working as expected for the versions mentioned above.
Cheers,
Ismael
