Comment 3 for bug 1822329

Initial phase of the rewrite has been completed and tested. Trusty support has been removed because snaps cannot work on trusty containers, and layer-snap returns an error instead of blocking the unit.

I will link another MP once it is ready, adding unit and functional tests for the different modules. Once approved, I think the "rewrite" branch could be merged into "master" to start fixing bugs directly into the main stream.

Plan is to file different bugs to reduce the usage of sqlite instructions and use the API or new features from v5 and on (ie. provisioning feature, for static datasources [pulled from relations] and dashboards [rendered from included templates]).
