Implementation plans:
I think we've thought that user intent should be done by whoever the
first consumer ends up being. Looking at the above proposal though, I
think it's a large enough amount of work that it is reasonable to do it
separately. Further, the sooner we start tracking user intent, the more
we'll be able to do once consumers start appearing.
Within this work, I think there are further divisions that can be
reasonably made:
1) add intent tracking from this moment forward and get the storage
infrastructure in place and work with the install team so that newly
installed systems either have empty user intent or the desired user intent
2) Add the historical inference of user intent as well as the default
info for packages.
3) Give packagers the ability to control the propagation of user intent
4) Give users the ability to change the intent for a package
5) If for expedience, the decision in step 1 was to have the installer
provide empty user intent, then fix that so appropriate intent is
delivered.
Those are my current plans and thoughts. I'd appreciate any comments or
suggestions.
One last item I failed to mention:
Before this work is done, image versioning need to be implemented. The
changes you've proposed within are essentially a change in image format
and that means that older clients attempting to manipulate an image
created by a newer client won't work quite right or will cause loss of
this additional information.
As such, it would be great to see a proposal for an image versioning
scheme and a dependency on that. If it can go back first, that will
help ensure that older clients aren't used to manipulate images created
by newer clients. Obviously we can't do anything about clients that
don't have versioning checks, but it is a step in the right direction.
And possibly that change could go back to the sustaining gate as well to
ensure there aren't problems going forward?
