On our production server we have 2 instances of the same module, their techincal names are l10n_dk and l10n_dk_custom.
When i look in our folders specified by odoo.conf, i can see two modules named l10n_dk, one in each folder /odoo_dev/addons, and /opt/odoo/addons. While i think that the module called l10n_dk_custom is one that works as attend, since i cant get l10n_dk to work on a test server but l10n_dk_custom does. It would be nice to find the module l10n_dk_custom.

I have tried to use find -name l10n_dk_custom, but nothing is found, so im wondering what to do.

I have looked in the manifest of the two modules i can find in the different folders but none of them refer to l10n_dk_custom.
