When looking at the Linux code it seems that the TUNSETIFF ioctl(2) is
mandatory to have the interface created/attached, and that in the case
of a supplied IFNAMSIZ sized string it'll apply the name at interface
creation, not rename it after creating it automatically at open(2)
time.  Thus avoiding the possible race condition I mentionned IRT a
system that'd track interface creation.
