-The man-page of 'loadkeys' explains a possible side-effect of changing the keyboard-layout in the console.

-The package //kbd// has a almost one hundred dependencies going back to, e.g. //passwd// and //mount//. Thus it is desirable to include it into a base extension rather than used it as an isolated extension as here presented. That may be done at a later time without need for repeating the whole procedure. +

-====Notes====+===Notes===
   *The naming scheme remains a bit hazy. The Swiss-German layout, for instance, may well be loaded by 'loadkeys ch' but the command does not produce any output. Indeed, there is no file 'ch*' at all but instead one for 'sg_latin1'. YMMV. In the end, the file names do not matter as a new key-map file for local use is generated anyways.   *The naming scheme remains a bit hazy.
