How ever it is done it is too much to have at install, and too error prone.
Maybe there somewhere could be a simple link to our wiki pages. "To access your files from other operating systems, after install search our wiki for "acessing other partitions" URL here. That link could also be shown in control centre where users are handled. And in the wiki we can have all explanations, and possilbe also code snippet examples to paste/edit to a terminal to change user UUID/GIS, mount other home, etc, and update and extend it whenever needed. (And generally i thinkit is a good idea to put much documentation in the wiki and point to it from various places, but there should also be backup information when interent is not available... local html files?)
