Description of problem: The kbd of RedHat 9 doesn't include fr-latin0 keymap! Of course, and however, this keymap can be chosen in redhat-config-keyboard and during the installation. Actual results: It will result in a failure when trying to load the keymap (since it's not there!). Expected results: fr-latin0 should be there!
In fact fr-latin0 is present BUT it has been renamed to fr-latin9. There is a probleme there, because all programs in RH9 use fr-latin0 name (all keyboard configuration programs including installer), so they will happily allow configuring this keymap with a name that doesn't exist since it has been renamed. Solution: either modify all keymap configuration programs in RedHat, or simpler, rename back keymap fr-latin9 to fr-latin0
