Then, I think, its time for me to volunteer and try to make the best of it 
in future. I understand, my mail has been a little too aggressive, I didnt 
want to discourage you from doing _your_ volunteer work.

I wrote this mail in a mixture of urge to let it out and hope someone here 
at the list has an idea how to quickfix the situation.

Its nothing personal. I just feel discomfortable by the fact, that your 
mistake (hey, everyone makes mistakes) has made it into a release, 
apparently without any testing. Shouldnt there be a Q/A? Thats why I put 
the mail on list, not to embarrass you.

Sure its works, its even a thing I would everyone encourage to do. Its
always a good idea to seperate services, even if you only have one IP.

Ehrm, your test failed ;) So its just a matter of luck, you dont always 
delete the IP from all interfaces.

There are other (imho better) solutions for the problem (I dont even 
consider one, anymore).

Again, its not your fault. And theres no need to take it personal. I just 
didn't want to let this pass. Hopefully there will be a working Q/A in 
future. I make mistakes, too, made them in "pet" projects as well as in 
projects I am paid for. And I don't think that users of my open source 
projects deserve less means to express their anger than my costumers.

Still, I do not think the jail_if feature is a good idea, I even consider 
it contra-productive. But thats not subject to discussion, anymore.

You may have had received them a lot earlier, though.
