This looks like a duplicate of #29906 to me.

Absolutely. Don't know how I missed that. Whoever wants to investigate this, the obvious fix of adding -r to

nixpkgs/nixos/modules/services/logging/logcheck.nix

Line 11 in 6dbe55c

rm $out/logcheck.*

"fixes" the problem. I didn't investigate if I want that folder though.
