Bug#807945: keyboard-configuration skips prompts when using only bluetooth keyboard

[bunnie <bunnie@kosagi.com>]

Package: keyboard-configuration
Version: 1.123
Severity: normal

Dear Maintainer,

When configuring a system that uses only a bluetooth keyboard (no USB keyboard
directly attached), the function keyboard_present() in keyboard-configuration.config
indicates that no keyboard is present, which prevents the keyboard configuration UI
from ever running. 

The work around was to plug in a USB keyboard temporarily while running
dpkg-reconfigure keyboard-configuration, so that the function would return
true.

It might be nice if the script could work with bluetooth keyboards, or perhaps
at least emit an error message to console indicating that no keyboard was detected
therefore the configuration UI is being skipped. It took me a long time to figure
out that's why the script wasn't working. This is in part because I spent a lot
of time trying to figure out the significance of these warnings, which I think
are harmless red herrings in the end:

# dpkg-reconfigure keyboard-configuration
update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults

thanks.

-b.
