condarc-file keys are overwritten

[borchero]

When specifying condarc-file, this action copies the file over to a default location and then appends a couple of keys (e.g. channels). When specifying these keys in the condarc-file, they are overwritten as there are duplicate keys in the .condarc YAML.

Do you mean that we override keys that you would like to preserve or that we override the entire condarc file?

[borchero]

Imagine I have a condarc file like the following:

channels:
  - conda-forge

Then, this action will create the following ~/.condarc file:

channels:
  - conda-forge
channels:
  - conda-forge
  - nodefaults
# and some more configuration options...

I.e. depending on the keys I have in my custom condarc file, this action overrides particular configuration options.

What are the specific options that you care about? channels?

[jonashaag]

What are the options that you pass to provision-with-micromamba? If I'm not mistaken we don't add nodefaults to the list of channels

I think this is fixed in https://github.com/mamba-org/setup-micromamba.
