There was a problem hiding this comment.
@ls devs: Just be careful when using LAMBDA_INIT_USER in combination with init debugging.
We could also consider flipping this 🤷

Depends on localstack/lambda-runtime-init#26
Motivation
This PR simplifies the user's configuration in the Lambda init Go binary. We drop root privileges in the Lambda init Go binary by default and offer a configuration variable to skip this parity feature. However, it is cumbersome to configure using a misleading empty string
"". We skip dropping privileges whenLAMBDA_INIT_USERis set toroot(""is still supported but discouraged).This is much easier to configure and leads to less errors around escaping quotes etc.
