Package naming conventions

From NixOS Wiki

When looking through the available Nix packages, one might find some naming conventions.

Suffix Use
-bin The binary is copied from upstream, not build from source using Nix. A -bin version is only available if a source-based version already exists, and there exists a meaninful difference between the two. An example is the Hashicorp Vault package that doesn't include the web UI, but the -bin version does.
-unwrapped Some packages provide options for customization that don't affect the main build, and is thus done in the -unwrapped package. The package is then wrapped to provide customization without having to recompile the package. This is an implementation detail, you generally don't want to directly use an -unwrapped version.
