I recall in some cases it is also necessary to regenerate initramfs 
after a keyboard settings change.

E.g. when LUKS encryption is used and the user needs to be able to enter 
the password to unlock the disks in the console prior to the rest of the 
system being booted.

So just restarting one of the services actually may not be enough.
