[Nix-dev] ZFS on NixOS regarding the `/etc/zfs/zpool.cache` file.

[Roger Qiu]

Hello,

I found the commit relating to my problem: 
https://github.com/NixOS/nixpkgs/commit/12e77fdc3f6f223be1a4d5c88d6c79bff63ae70c#commitcomment-10932244

I made a comment regarding the lack of zpool.cache file. It's required 
for `zdb` to work. Perhaps we can generate the `zpool.cache` file at 
startup?

Thanks,
Roger
