Caching `/nix/store` is ok, but unable to restore it.

See original GitHub issue

Hi,

I’m trying to improve the workflow in here: https://github.com/hmemcpy/milewski-ctfp-pdf/blob/master/.github/workflows/build.yaml

Basically I would like to cache the build dependencies once, and re-use them in each book editions (8), so there is no need to download 8 times the same thing.

Caching the /nix/store directory works: https://github.com/drupol/milewski-ctfp-pdf/runs/5348859880?check_suite_focus=true

Restoring it fails: https://github.com/drupol/milewski-ctfp-pdf/runs/5348868521?check_suite_focus=true

Do you have any idea on how I could fix this ?

My solution is unnecessarily slow and complicated.

This issue could be resolved easily by running the tar in the creation and untar in the restore with root privileges using sudo. Is this not an acceptable solution?

This would also solve #629 and #324 .

Do you think it would be a good idea to automatized these steps the Github Action (https://github.com/cachix/install-nix-action) from @domenkozar ?
