func HostnameMapper ¶

func HostnameMapper(ctx context.Context, input []types.Value) (types.Value, error)

HostnameMapper takes a map from mac address to hostname, and finds a hostname that corresponds to one of the mac addresses on this machine. If it cannot find a match, it returns the empty string. If it's ambiguous, it errors. This is useful for bootstrapping the hostname setup on hosts.

XXX: This should produce new values if the list of interfaces change.
