CAP_SYSADMIN or somesuch should be required for some of those IOCTLs, at least on keyboards. I don't see a problem with a digitizing tablet relaxing that to allow anyone, for example, so it makes sense to punt this test to the driver level (and not input layer level), or to make it configurable somehow from the driver level before registering the input device. > Anyway, I think that we don't want ordinary users to alter hardware > keymapping, it should indeed be priveleged operation done by box's > administrator.

Oh yes, it *is* used, and very much so. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
