Alsroot,
Somethings to keep in minds while you are working on these policies.
1. Right now, the code churn rate is very high. In the beginning,
all projects have high churn rates which settle down as the product
becomes more stable and widely used. Issues which seem large right
now will fade away as Sugar stabilizes.
2. If Sugar Lab's 'distributes it' we will need to support it.
Supports cost are high, particularly when testers have to isolate
which variants have issues.
3. School seldom update their software more then once every two years.
For the last two releases we have been focusing heavily on the needs
of the developers. Now, the development process is running well. I
encourage you to focus on, 'What policies are best from a long term
maintenance and and support point of view.'
Don't worry too much about getting the policy 100% correct the first
time. They can be updated and improved.
These policies are essentially agreements between core developers and
activity developers and agreements between Sugar Labs and down stream
about what to expect.
thanks
david
