Here is a design proposal for altering the installed layout of application bundles to be suitable for upgrade/rollback, data-reset, containerization, and the theme installation use-cases raised by Ramya and Suma on <https://bugs.apertis.org/show_bug.cgi?id=575>: <https://wiki.apertis.org/Application_Layout> Please let me know if there are any requirements that are not covered, or areas that are unclear or unsuitable. There are some unresolved questions about the requirements, for which I would particularly appreciate feedback: <https://wiki.apertis.org/Application_Layout#Unresolved_design_questions> The part discussing icon themes should eventually be split out into a separate design document that specifically covers what has been said on <https://bugs.apertis.org/show_bug.cgi?id=575>, but for the moment it's just a subsection of Application_Layout.
