Can I add a suggestion?
How about maintaining a (few) working Virtual machine snapshots? Since so many of us has the capability of running either VMWare, KVM or Virtual Box it could perhaps improve vastly on the resource pool for debugging etc. This will of course not test the install script in its own right, but accelerate the path to more mature core distros, and even allow for easier route to getting physical MDs to work.
This could flatten the learning curve for newcomers... Something worth considering, I believe many potential users (->testers --> contributors) have been lost due to not even getting through 1st install of the most mature beta/DVD snapshot
I have VMWare and would volunteer to create a snapshot (VMWare calls it a "Virtual Appliance") - do we have proper filespace to upload these? (my upload is only 2Mbit, meaning I can not host myself). It would probably be worth just keeping a few WM snapshot, rather than 50 DVD install snapshots...
I will of course get to that snapshot via the installer script, but probably not do create_diskless (no point before installing dvd-libs). It should be a very small issue to then make a wiki (with few pitfalls) for how the setup the virtual NICs, add dvd-libs and run create_diskless, and then new testers could have a working core in no time... I could even write a wiki for how to increase Virtual Disks (since it is a no-brainer in a virtualized environment), should some choose to keep their test install and run a "production core" from that..
In the end, we should be interacting more with the MD than with the core
(and a working 10.10 is probably the better route, even that my 8.10 is acting OK so far - but I haven't received my new USB DVB-S cards yet, they could force me to 10.10 sooner than later)
