We have three moving pieces that could, in theory read and write the
same settings:

* ArgyllCMS
* Oyranos
* colord

If I understand correctly, Oyranos and ArgyllCMS run in the user
session context only, and colord runs in the system context only.

* If Oyranos writes to the user ~/.config/color/settings/ how is
colord supposed to know that settings have changed?
* How is argyllcms supposed to set a specific profile to be used on
the login screen if it can't write to /usr or /var?
* If colord sets a new system-wide profile to be used by all users,
how is it supposed to remove or nullify the entry in ~/.config that
will override it?
