I'll try to fix this.

/assign n0npax

It also includes kubectl for linux (for uploading to the node, at least)

If you want to download kubectl for the host, it might need a download.

I'll unassign, as seems it requires a little bit better understanding of the project.

I think it was almost done, just that we missed that kubectl was also in the preload.

i.e. there is one kubectl for linux, that is in the preload and that we install to the node
then there is one optional kubectl client for host OS, that we download on demand
in this case, we want to skip downloading the kubectl linux that is already in the preload
should also make the code easier, since it doesn't have to special-case like before ?
