Re: Requalification of Alpha for etch

I've never paid much attention to what goes into the buildd system, so these may be very naive questions, but I'm curious:

Why is so much attention required? Is it for stuff that can't be automated, or just hasn't been? (Aside from the really obvious, like hardware issues.)

From my point of view it's less about constant care (security updates) than fast response time. If a severe kernel exploit is found James Troup deactivates the logins and drops you a note that a new kernel is needed. A couple of days until the upgrade are ok, but it shouldn't take weeks.

The building as such is fully automatic, Ryan Murray will care about that.

Can multiple, lower-powered machines help? I'll probably be getting my hands on another alpha system soon, a 400AU I think, but it sounds like that may not be fast enough?

One extra high power Alpha would definitely be easier to maintain :)

(I've also got spare cycles on another alpha-linux box, and if we had an Alpha equivalent to Xen, I could spare cycles from my alpha- netbsd box too.) No GS320s on the horizon for me.

I can't tell you anything about running a buildd on a private machine, but in order to get redundancy we'd need a second Alpha which can do security builds... and the security team wouldn't like that to be on a private machine :-)

I'd like to help out, but don't have the biggest amount of resources to contribute, nor lots of my time on an ongoing basis, so it never sounds like it's worth getting into it. But if I it were just a matter of "oh, we wedged the machine again, please hit the reset button and boot off the Buildd Live CD when you get a chance so you can rejoin the build cluster", then I'd probably pursue it....

I had to promise my new employer that maintaining the build machines wouldn't take too much of my work time and I had no difficulties doing that. It's a bit more than pressing reset (especially if new exploits appear...) but otherwise not much after the initial installation. Maybe you could care about a donated high power alpha if Steve picks one?
