Failed to extract archive error for 6.6.47 kernel package

[mroi]

When I run this command to fetch the 6.6.47 Raspberry kernel image, I get an error:

nix build github:nix-community/raspberry-pi-nix/351301b1a13c108f5cb9d7b7b1f813583d3b5d10#packages.aarch64-linux.linux-v6_6_47-bcm2712

The error message:

Has anyone an idea, what could cause this? My Nix debugging skills are failing me here.

I believe this issue is caused by me extracting to a case-insensitive file system. Extracting a Linux kernel can fail, because it contains files whose names differ only in case.

I was running this on a macOS machine. My Nix store is already situated on a case-sensitive volume, but since the kernel source is an input to the flake, I believe the download is first staged in $TMPDIR, which pointed to my case-insensitive default data volume. Changing $TMPDIR to point to a case-sensitive directory fixes the issue.
