s/spec.UTS/rspec.UTS
I think we don't need this variable, we can just popup an error here if hostname is empty.

This probably needs the whole rspec.Spec, not its current rspec.Linux. Then you can check spec.Hostname and spec.Linux.Namespaces. With cross-platform options like ‘hostname’ depending on platform-specific options like UTS namespaces, this kind of cross-cutting is unavoidable.

@Mashimiao sorry, your first commit is right.
On Linux, you can only set this if your bundle creates a new UTS namespace.
So host name could be empty even a config file has a UTS namespace.
We should get an error when hostname is empty and no UTS namespace is created.

Correct. Maybe the UTS namespace is for a NIS domain name.

I think you mean, when the hostname is not empty and no UTS
namespace is created. All other combinations (UTS and no hostname,
neither UTS nor hostname, both UTS and hostname) are valid.

Yes, when hostname is not empty.
@Mashimiao 's first commit did the right thing and I mislead him to squash code lines.

"hostname requires a new UTS namespace to be specified as well"
