# NOTE(claudiub): We're creating symlinks for each of the busybox binaries and after that we're copying
# # them over to Windows. Unfortunately, docker buildx has some issues copying over Windows symlinks.
# # "Files/" is always prepended to the symlink target. The symlinks themselves are relative paths,
# # so, in order to make use of them, we can simply add a busybox binary to Files\busybox.exe.
