[tex-live] Has anything changed in the order TL searches for packages?

[Urs Liska]

Hi Norbert,

thank you for pointing this out in more detail.

After your earlier post I had already tried to follow your solution - 
but with a mistake: I created an additional link in ~/texmf/tex/lualatex 
instead of ..luatex. Now that I changed this it finally works.

I have now created *two* symlinks to my latex-git directory, from both 
~texmf/tex/latex and ~texmf/tex/luatex, and I hope this won't create 
other conflicting situations down the road. For now it works, and I know 
I'll have to do a lot of work explaining this in the Contributors' Guide 
(where the project set-up is already somewhat "fragile", with numerous 
variable elements ...).

Best
Urs
