Unfortunately I'd chosen the jargon word carefully for its usefulness
as a way of equivocating... you may not be safe using one wired and
one wireless card, since in very rare cases the kernel may misclassify
them as eth0 and eth1; but as long as it's only putting one interface
in each namespace you *are* guaranteeably safe! (Or at least, you're
safe from them coming up as eth1 and eth0 the next time; you aren't
safe from finding they've turned into eth0 and wlan0. But the
"predictable names" system doesn't protect you from that anyway; the
only thing that does is identifying them by MAC addresses.)
Another way of phrasing it would be to say something like "only one
network interface recognised as belonging to a given type (e.g.
ethX)". But that's getting too contorted. Maybe it would be better
to simplify down to this:
On systems with simple network hardware (e.g. only an
<literal>eth0</literal>
and no <literal>eth1</literal>) the <literal>net.ifnames=0</literal> kernel
commandline option should also work.
