Edge is just a point on the roadmap. If staging is fast enough to
scrap/deploy then we may just use staging all the time.
I was actually thinking it might be nice to have staging as more of a fluid
concept using VMs. We could set up a semi-permanent staging VM that gets
updated with trunk of everything every {day, week, whatever}, but also have
other VMs available for upgrade testing, and testing individual changes.
That way, for instance, if you need to test a dispatcher change that
affects a certain type of board you don't have at home, you can simply wait
for one of those boards to become available in the lab, mark it offline,
bring up a vm and do some testing with it. Likewise, it could be used to
setup and test an invasive change to the dashboard. All that would be
required is a few static port mappings on the firewall, and a server capable
of handling a few KVM sessions (which I'd like to look at getting soon for
this purpose and others).
I agree with usefulness of staging as a fast-to-production model While
using VMs is a possibility it does not really preclude me from
experimenting with this design.
For safety reasons a VM might be needed once we start to run stuff as
root. Currently all edge stuff is owned by a normal user and runs as the
web server.
One thing that worries me is KVMs lack of (can anyone correct me if I'm
wrong) USB pass-through support. This means we may have a hard time
reaching USB serial adapters or USB-to-device links in general. For that
reason my testing will use headless virtualbox instances.
I have created lp:~zkrynicki/+junk/edge where this stuff is being created.
Thanks
