Subject: [PATCH] localed: match converted keymaps before legacy
Before, X11 keymap fr-pc105-oss would be converted to fr,
even though fr-oss exists. Now, if
/usr/lib/kbd/keymaps/xkb/<layout>[-<variant>].map[.gz] exists,
<layout>[-<variant>] will be used as the console keymap,
falling back to the legacy mappings otherwise.
