The zip file produced by AssetArchive seems to dereference symlinks and replace them with duplicates, which can produce a larger output archive. Is there any way to recreate the

-y

symlink-preserving functionality?

That's not currently supported, and the Go archive/zip library we use doesn't look like it has built-in support for it. But feel free to raise an issue at https://github.com/pulumi/pulumi/issues about it.

Thanks Fraser, I’ve opened this issue: https://github.com/pulumi/pulumi/issues/9465
