I think Mr. Renaud had a little flaw of thought while writing,
but yes, I can confirm the behaviour indeed is erroneous or
quite surprisingly tweaked:

The whole interface is dropped when you down eth0:42 and have
a standard IPv6-tools package. At least this was the case on
all Linux-boxes I attempted this on (admittedly most of them
were the same breed, though).

I had been able to take advantage of the exact same set of
commands on my IPv4 boxen earlier. I am not, however, aware
of the exact cause for this.

As a matter of fact, this was some weeks ago, on a cosy Sunday
morning, me using a production-box at work to perform what I
thought would be a normal peaceful administrative procedure
that I can quickly take care of while at home.... ,)

Though, I doubt anybody mind the eth0 being down until late
afternoon...
