It actually depends upon the requirements of the particular aircraft - I've flown some that require the ignitions to be "ON", and others where it's only necessary to to keep them in "AUTO". The requirement, when required , is to make sure that you keep the "fires" burning in the event of a sudden large power-lever movement - say, for example, a go around. The same thing goes for takeoff, some aircraft require you to use ignitions, other don't. The other times where you'd want to use ignitions is during moderate or greater turbulence and in heavy rain.

On the 757, with AUTO selected on the engine start panel (the standard setting after engine start), the selected igniter(s) will operate continuously whenever the flaps are extended to any angle away from zero, and/or engine anti-ice is on.
So we have no need to make a new selection prior to landing.
I used to love the smell of Jet-A in the morning...
