I am using miniconda with tectonic to use continuous integration which works awesome, but installing the LaTeX packages every time takes a long time. I have successfully cached miniconda, however tectonic still installs packages on every run - I would like to cache those as well.
Which folder do I need to link to in my cache such that the LaTeX packages are retained and tectonic recognizes that?
