Title:
  Provide easy way for OEMs to override default settings

Status in “d-conf” package in Ubuntu:
  Invalid

Bug description:
  Part of the requirements is to allow the OEMs to be able to override
  some settings that are stored in dconf (for example which lens pages
  in the dash are visible by default). Usually we'd just add a new
  .override file into /usr/share/glib-2.0/schemas, but this will not be
  possible for the OEMs as any changes they make will not change the
  base Ubuntu image.

  A solution that we agreed upon is to extend our XDG_DATA_DIRS (we'll
  prepend a new "/custom" path to the dirs where the OEM's overlay will
  be mounted), but since dconf doesn't support this type of layering
  (real schema in /usr/share/glib-2.0/schemas and possible defaults
  overrides in /custom/...), we decided to add a symlink in
  /usr/share/glib-2.0/schemas/xyz-oem-gschema.override which will point
  to the override file in the OEM overlay ("/custom/..." - TBD).

  Once we have the override file in place, we need to recompile the
  schemas (by invoking glib-compile-schemas), to make sure the new
  defaults are accounted for, although this will have to be done in a
  boot script (ideally with a stamp file so we don't unnecessarily
  recompile it on each boot).

  With this solution we allow the operators to change default settings,
  while still being able to upgrade the base image and change the
  shipped schemas (but keeping the OEM overrides in place). Plus if the
  operator ships applications that have their own schemas, this is still
  possible by compiling a separate set of schemas in the overlay. And on
  top of everything we don't need to change our apps/daemons to check
  special OEM schemas that might and might not be installed.
