Please see the repo readme for directions on how to make PRs on this repo.

Checklist:

• [x] if you have added a CDT, it appears in the cdt_slugs.yaml file and you have rerun the script python gen_cdt_recipes.py.
• [ ] if you have changed the CDT generator code (rpm.py), you have bumped the build number in conda_build_config.yaml and have remade all of the recipes via running python gen_cdt_recipes.py --force
• [ ] if you have added a custom CDT recipe, you have added the name of the CDT with custom: true in the cdt_slugs.yaml file.
• [ ] all CDT recipes have build number set by {{ cdt_build_number }} for old-style/legacy CDTs or {{ cdt_build_number|int + 1000 }} for new-style CDTs
• [x] if you see a warning about a CDT not having a license, you have added the license_file key in the cdt_slugs.yaml file with the path to the appropriate license in licenses/

NOTE: If you make any changes to cd_slugs.yaml, you need to reun the generator code via python gen_cdt_recipes.py. Add the --fast option to make this go more quickly.

Apart from the ones added to cdts_slugs.yaml, this also added kmod -- shall I add it to the YAML file, too?

It is not formally required but it can be useful if you don't want to build this CDT on all platforms and centos versions.

So kmod is only available on CentOS 7, so we won't have to skip for 6 :) (and having it for ARM/PPC is fine, of course). If you think it's good to add it to the list explicitly, then I'll happily added it; if not, also fine by me -- you're the expert here ^^.

Is there anything else I could've/should've done here? I never added a CDT recipe, hence asking. Essentially, I just added the skip/license fields/files and ran the Python script, but nothing else :O.

The PR looks good and I cannot remember anything else that needs to be done. The code can be a bit finicky when making new CDTs. Sometimes you have to run it more than once. I'd say we merge and hopefully, the things you need get built. If you find they are missing, we can revisit.

[mbargull]

Alright, thanks for having taken a look at this (and that you've automated it to be used so conveniently)!

[beckermr]

Looks like the api key might be old. I will update it and rekick the builds.
