Just checked Trisquel GNU/Linux behaviour. Installed latest Triskel (KDE variation) in VM, results:
$ sudo dpkg-reconfigure keyboard-configuration [sudo] password for pioruns: Your console font configuration will be updated the next time your system boots. If you want to update it now, run 'setupcon' from a virtual console. update-initramfs: deferring update (trigger activated) Processing triggers for initramfs-tools (0.130ubuntu3.13) ... update-initramfs: Generating /boot/initrd.img-4.15.0-156-generic I: The initramfs will attempt to resume from /dev/dm-2 I: (/dev/mapper/trisquel--vg-swap_1) I: Set the RESUME variable to override this So they have update-initramfs after keyboard-configuration change, and very informative message about what's going on. Debian should have that too!
