Re: virtual interfaces not routing properly.

Please don't call ethX:Y virtual interfaces. They are not interfaces.
Only ifconfig artificially treats them as interfaces. They cannot be
used as interfaces by other tools nor by the kernel.

That sucks big time. Don't tell me it is the new official way to replace
aliases. This is just an ugly hack to work around ifupdown's lack of
ability to assign more than one addresse to an interface. IMHO it would
be much better to upgrade ifupdown, for example by allowing the
'address' option to contain several address/prefixlength values, or
multiple 'address' options.
