While we were talking I updated lemmy-server using overrideAttrs for my own use. It’s honestly not that hard. You change the commit, specify some random incorrect hashes, build it, nix screams at you that the hash is incorrect (and generously provides the correct one), put the correct hash, and build again. Done.
The hash isn’t there for security, it’s to make sure the code you’re building against doesn’t randomly change which could make the derivation fail to compile.
For example, for the source, you can specify a literal HTTP download from a URL, and that file could be changed by the host at any given time, so it’s there as a safeguard.
