It's not something we have to worry about until next year, but seeing photos of two of my nephews on their first day at school, as well as various children of friends, made me remember my first day back in the (very) early Eighties.
Leaving aside the whole "you aren't actually registered with a class because your mum sent you to this school despite being told not to as you aren't in the catchment area, so when the whole year gets their name called out and moves one by one to their designated teacher you will be left sitting alone in the gym" scenario (it wasn't traumatic, mum, I only put two and two together about 20 years later) there was also the "homes, dinners, sandwiches" register.
Basically, once it was established each child was present and correct every morning, our school read out everybody's name again, and you had to reply "dinners" if you were having school dinners, "sandwiches" if you had brought a packed lunch, and "homes" if your mum was picking you up to feed you lunch at home. The roll call on the first day went something like: "Alison Abberton?" "Sandwiches." "HackneyHackette?" "Dinners." "Nicholas Brown?" "Sausages." "Sorry? " "Sausages." "No, Nicholas, you have to say sandwiches, dinners or homes." "But I don't have sandwiches. I have sausages." He did as well.
