This command is supposed to set the virtual console keymap.

Helptext:

Commands:

  set-keymap MAP [MAP]     Set virtual console keyboard mapping

However it changed my X11 keymap configuration file.

Afterwards I checked the manpage and find:
~~~
           Unless --no-convert is
           passed, the selected setting is also applied to the default
           keyboard mapping of X11, after converting it to the closest
           matching X11 keyboard mapping. Use list-keymaps for a list of
           available keyboard mappings (see below).
~~~

Now this is totally unexpected and doesn't make any sense at all.
I didn't check the --no-convert option beforehand, because it's - unexpected.

Even if there's a friendly intention behind this, it just feels like: "You just got screwed!"
What were you thinking, when you programmed this ?

Please, clarify the description in the help text or change the behavior.

Thanks

Thanks for improving/fixing (despite my provokative report).
