i am also interested in this -- i can't run buildpacks right now because this image doesn't have /bin/sh:

https://github.com/buildpacks/pack/blob/main/Dockerfile

Is there a workaround in the meantime?

You would have to create a plugin from the underlying docker image as plugins are using predefined commands and entrypoints.

Is there a workaround in the meantime?

# wget https://raw.githubusercontent.com/buildpacks/pack/main/Dockerfile
# sed -i 's\FROM ${base_image}\FROM gcr.io/distroless/static:debug\' Dockerfile
# docker build -f Dockerfile .
