Seems like I've missed a discussion on IRC. Please don't read my next
lines as stab into your back.
First of all I don't understand the problem you want to solve with this
solution. In the past we had people who monitor the
security at archlinux.org address and I had always the feeling that they
did their job good and had no problem with doing it. I always thought
that there are not so much mails with security at archlinux.org as
recipient. So either my observation was wrong or things has changed..
Let's say the workload has increased. Then I am fully with you and I
can understand your problem. On the technical aspects I like your idea,
but I can understand Florians point of view as well. Maybe the problem
could be already solved via creating a security landing page with a few
developer mail addresses and their GPG keys.
But here is another argument for the server:
We could use it as isolated machine for automatically signing ISO images
and Arch Linux images.
