Bug#473217: Wishlist: Don't run ckbcomp at boot-time (use a saved keymap instead)

[Alan Jenkins <alan-jenkins@tuffmail.co.uk>]

Package: console-setup
Version: 1.16
Severity: wishlist

The setupcon command, as run by console-setup during boot, runs ckbcomp 
to generate a console keymap from the X keymap files.  This can take on 
the order of half a second CPU time.

setupcon already saves the resulting keymap in 
/etc/console-setup/boottime.kmap.gz, and has support for using that 
instead.  However this is only used when /usr is not mounted.  I'm not 
interested in repartitioning my system to use this feature.

My wish is that this method would be used even when /usr is mounted.  It 
may require some documentation but I think it's sane enough.

It looks like Ubuntu (my primary OS), have altered the console-setup 
init script to regenerate the keymap if run manually (i.e. not by init):

# Are we running from init?
run_by_init()
{
   ([ "$previous" ] && [ "$runlevel" ]) || [ "$runlevel" = S ]
}

...
	elif ! run_by_init; then
	    log_action_begin_msg "Saving console font and keymap for next boot"
	    if setupcon --save-only; then
		log_action_end_msg 0
	    else
		log_action_end_msg $?
	    fi
	fi

So if you edit /etc/default/console-setup manually, you then need to run 
"/etc/init.d/console-setup restart" to apply the changes and regenerate 
the keymap.  This happens automatically when dpkg-reconfigure is used.
