How to clearly define dependencies?

As, e.g., Git LFS is quickly evolving, we need to clearly define the dependencies.

I did all my tests with conda-forge/git and conda-forge/git-lfs.

Using a conda env for deployment and all / many of the tasks in the repositories themselves would also benefit from the usually up-to date conda-forge packages for netCDF, CDO, NCO etc.

@all: What do you think?
