error: hash mismatch in fixed-output derivation #31

Closed jfly closed 1 year ago

I put together a simple repo here:

Sadly, this is expected. I have expanded the section in the README.

Ah, that updated README is very helpful, thank you! I had seen that section before and totally ignored it as a "this is only relevant to folks developing nix-openwrt-imagebuilder itself, not someone who just wants to use it". Now I understand why it's important!
