Looks like terragrunt swallows the -backend=false flag during init ops. We need this to run linting against the codebase on an execution env that has no credentials.

~ terragrunt init -backend=false
╷
│ Error: Backend initialization required, please run "terraform init"
│ 
│ Reason: Initial configuration of the requested backend "s3"
[...]
~ terragrunt init -backend=false --terragrunt-no-auto-init
╷
│ Error: Backend initialization required, please run "terraform init"
│ 
│ Reason: Initial configuration of the requested backend "s3"

However, with terraform directly:

~  terraform init -backend=false

You can achieve the same result using an environment variable and the remote_state.disable_init attribute.

As per the documentation:

Running into the same and the disable_init option doesn't fix it. I'll have to prolly add the credentials just to be able to validate which sucks as it works out of the box with plain terraform.
