I think that adding anything like HOSTSPECIFIC is a failure on our part. That means that you need to make programs out there aware of multiple hosts and their usage. You can't just say that you going to teach X and the rest will use X facilities because there is world outside of X. Programs like HAL, network management (rfkill) other daemons getting input directly from /dev/input/eventX will have to be made aware. This is not good. I really don't like KEY_FN_F1..KEY_FN_BACKSPACE either. What are they supposed to do? Just being an unique value to be mapped onto something useful? But why not use that useful keycode to begin with? I'd rather leave the keys unmapped and rely on initsripts (possibly with help from distributions vendors) to load proper keymap then add something that must be retranslated over and over again. > > > Really, what are we to do with that input.h scancode map?

You, as a maintainer, can chose defaults. Since you (well, not you, the driver) provide a way for a user to adjust keymap there should be no problem even if someone does not like the values you chose. Having sensible defaults is a good thing, otherwise many people will not even know that they have these "separate" keys. > > Alternatively, if you let me add keys, I will need a few of them, and they > are also generic (not necessarily thinkpad-specific).
