Answer / sjtbehera

There is very little that you can do, to prevent a plaster
ceiling from cracking. If it's going to crack, there is
nothing you can do to avoid this. However, these cracks can
easily be repaired using
Fiberglas drywall tape and finishing it with drywall joint
compound.

I have probably made this repair sound easier than it is,
but there is another alternative. You could fill the crack
with a good paintable caulking. Make sure that the caulking
you use is paintable, some silicone-based caulking aren't
paintable. If the caulking can be painted over, it will
save paintable on the tube of caulking.
