Slice definition components under 'v3-essential' are not fetched and extracted into the container image #262
Description
Slice definition components under 'v3-essential' are not being fetched and extracted into the container image.
Consider the following Dockerfile:
ARG UBUNTU_RELEASE=24.04
ARG CHISEL_VERSION=v1.3.0
FROM ubuntu:$UBUNTU_RELEASE AS builder
ARG TARGETARCH UBUNTU_RELEASE CHISEL_VERSION
SHELL ["/bin/bash", "-oeux", "pipefail", "-c"]
RUN apt-get update \
&& DEBIAN_FRONTEND=noninteractive apt-get install -y ca-certificates \
&& apt-get clean -y \
&& rm -rf /var/lib/apt/lists/*
ADD "https://github.com/canonical/chisel/releases/download/${CHISEL_VERSION}/chisel_${CHISEL_VERSION}_linux_${TARGETARCH}.tar.gz" \
chisel.tar.gz
RUN tar -xvf chisel.tar.gz -C /usr/bin/
RUN mkdir /staging-rootfs \
&& chisel cut --release "ubuntu-$UBUNTU_RELEASE" --root /staging-rootfs \

RUN cp /etc/passwd /etc/group /staging-rootfs/etc \
&& install -o ubuntu -g ubuntu -d /staging-rootfs/home/ubuntu
FROM scratch
COPY --from=builder /staging-rootfs /
USER ubuntu
WORKDIR /home/ubuntu
ENTRYPOINT ["bash"]
Per the current slice definitions in https://github.com/canonical/chisel-releases/tree/ubuntu-24.04/slices, the gcc_gcc slice should include the gcc-13_gcc-13 slice.
The gcc-13_gcc-13 slice should include gcc-13-x86-64-linux-gnu_gcc-13 slice when built on amd64. But notice this is under 'v3-essential'.
The gcc-13-x86-64-linux-gnu_gcc-13 slice should include the file /usr/bin/x86_64-linux-gnu-gcc-13.
However, when the Dockerfile is built and the container image contents are examined, the expected /usr/bin/x86_64-linux-gnu-gcc-13 file is not present:

If we build the Dockerfile with podman (which seems to have better console logging) we can also see that the gcc-13-x86-64-linux-gnu_gcc-13 slice is not fetched:

We can see that the same thing is also happening with the binutils slice, that is, no components under 'v3-essential' are being fetched.
