Test Failures After Running `nix develop` and `make test`

[byteshiva]

Description: After running nix develop followed by make test, the test suite encountered several failures. The errors seem to be related to the failure of services to spawn during the test environment boot process. The common error is "No such file or directory (os error 2)."

Steps to Reproduce:

1. Execute the following commands:

   nix-shell -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/nixos-unstable.tar.gz -p  rust
   git clone  https://github.com/fermyon/spin.git
   direnv allow
   nix develop ## not required 
   cargo build
   export PATH=$PWD/target/debug:$PATH
   make test
