Missing files in image built with Kaniko

[mpox]

Actual behavior
After building an image of given Dockerfile the java is missing in the image. Exactly same Dockefile built with Docker works fine. Interesting part is that adding RUN /usr/bin/java --version actually works and prints java version, but somehow finally the java is not in the image. It is also seen by size of an image. Incase of Docker, the size is around 650 MB, while when building with Kaniko, with exactly same artifacts it is ~100 MB less

Expected behavior
I would like to have all installed packages during building an image to be inside when running a container

To Reproduce
Steps to reproduce the behavior:

1. Build image of given Dockerfile using Kaniko (as artifacts directory provide whatever you want - just to make it build)
2. Run image and see how it fails with message

/srv/entrypoint.sh: line XX: /usr/bin/java: No such file or directory

• Build Context
  Contents of files/srv/entrypoint.sh

#!/bin/bash

set -e
exec /usr/bin/java --version

Contents of files/env and artifacts might be anything as modifiec version of entrypoint.sh does not use it.
Parameters for ARG may be anything as /srv/entrypoint.sh does not use them (I didn't wanted to affect reproducibility of this issue and I couldn't test reproducible Dockerfile without extra parameters)

Description	Yes/No
Please check if this a new feature you are proposing
Please check if the build works in docker but not in kaniko
Please check if this error is seen when you use --cache flag
Please check if your dockerfile is a multistage dockerfile

I have encountered the same issue with missing files when building images with Kaniko. This appears to be related to the --snapshot-mode=time flag which may cause kaniko to miss changes introduced by RUN commands entirely. To prevent this issue, you can use --snapshot-mode=redo or --snapshot-mode=full instead. redo is up to 50% faster than full per kaniko docs
