Thanks, wolfden.
This is the list of files I refered to as "Gentoo-standard", ( I browsed it already here: http://gentoo-wiki.com/TIP_List_of_Configuration_Files ) which is not a great help in some cases, as I described above. My interest was on the paths/files which are used deviant in Sabayon and also locations which don't show up in this list.
But for a quick first reference this list is helpful here, anyway.
