Kaniko deletes all content inside `$HOME` directory when using multiple `FROM` elements inside `Dockerfile`.

Actual behavior When I'm using multiple FROM <image name> inside Dockerfile kaniko somehow deletes everything inside $HOME directory (at least when running on root). Causing the push option of the image to error since the credentials are stored in $HOME/.docker.

Expected behavior Kaniko should build an image with multiple FROM <image name> elements just fine, without deleting content inside $HOME and pushing the image without any problem.

To Reproduce Steps to reproduce the behavior:

1. Install kaniko inside i.e. alpine container.
2. Install docker
3. Create credentials file with docker login
4. Create an example Dockerfile outside of $HOME directory:

FROM alpine AS builder

RUN echo "First image."

FROM alpine

COPY --from=builder /bin/sh .

RUN echo "Second image."

CMD ["/bin/sh"]

1. Build a Docker image and try to push it onto the specified docker registry (from docker login). Use command kaniko --context . --dockerfile ./Dockerfile --destination your.registry/username/package
2. kaniko should crash and after doing ls -a $HOME the directory should be shown as empty.
