Linux: detect network namespace and deny udev in one
udev says whether an interface name is stable or not.
In a network namespace, udev claims the interface does not exist.
This makes sense because udev only operates in the root namespace.
As such disable udev in a network namespace.
While here correctly spell initialise.
