The benefit of having t datamaps explicitly represented in the API is that it allows apps to determine which mappings are actually valid for a given OS. ie not all OS support all possible keymaps > > This ISO language extraction is just another example of the need for > > a general datamap capability IMHO, and while we only see it for Windows > > currently, I would not be suprised if other OS we encounter in the future > > need it too. > > > > I did actually start hacking up datamap support, but never finished it. > > Not sure there is really a need to do mapping in the code for at least > the installers.

Adding a new OS in the XML will just require adding a new datamap in the XML too. Never touching C code. The existing GVirInstallSCript class will automatically identify the required datamap and apply the mapping to properties being passed in Daniel _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
