Q: Programatically detect if 'conda-unpack' has already been executed?

[HenrikBengtsson]

On https://conda.github.io/conda-pack/ it says:

Once an environment is unpacked and conda-unpack has been executed, it cannot be relocated. Re-applying conda-pack is unlikely to work.

Is there a way to programmatically detect whether or not conda-unpack has already been executed?

I'm interested in this functionality as well. What I've been doing is building a tarball with conda-pack and having all bash script utilities I place in it run conda-unpack and write a <prefix>/.installed file that contains the absolute prefix path. Then any future executions I check if the .installed path doesn't match the current prefix I rerun conda-unpack. However, as mentioned in the documentation, this doesn't actually update the files that were updated in the initial execution.

I wonder if conda-pack could bundle a "package data" file that serves the same purpose as my .installed file. Theoretically this should give it all the information needed to know if it should run again. I think you could even use conda post-link scripts to create the initial version of this file with the conda environment's path: https://docs.conda.io/projects/conda-build/en/latest/resources/link-scripts.html
