The tweaks here are minor, Just documenting so that I will not forget. The changes relevant to me are:
-tzdata tzdata/Areas select Etc +tzdata tzdata/Areas select Asia
-tzdata tzdata/Zones/Etc select UTC +tzdata tzdata/Zones/Etc select GMT+8
-keyboard-configuration keyboard-configuration/xkb-keymap select gb +keyboard-configuration keyboard-configuration/xkb-keymap select us
One thing to note that it is through this that I know that the “|” character is not on the default GB keyboard layout, have to change it to the US Keyboard.
