This may have been discussed before…
When attaching drywall to a ceiling, it seems like a good idea to place the first screw about 6″ from the wall. Then when the wall is hung, it gets snugged up to the ceiling. Over time, that 6″ “gap” should reduce the chance of the corner cracking.
Did I read this here or just make it up?
I ask because I mentioned it to my BIL who has been in construction his whole life and he said he had never heard that before and doubted that it would make a difference. My feeling is that it COULD make a difference and is worth doing.

Depends on who you talk to.
I recently finished a remodel in a 1968 townhouse. Took out some of the rock on the walls for replacement. And when I did, the ceiling sagged, because the first row of nails was about 14" in from the edge.
New idea? -- maybe it was something you derived alone. But it's been done for decades, by others who thought of it too.

Gypsum acctually recommends 7" for single nailing and 12" for double nailing.

Thanks. The call it a "floating interior angle" and they say it may be used to minimize the effects of truss uplift. What they don't say is whether or not it serves any purpose for conventional framing. It seems that it can't hurt.
Yep, placing the ceiling fasteners several inches from the wall edge helps in the event that the wall and ceiling should go in opposite directions.
This is mainly important for interior walls in the top floor of a home with trusses, as "truss uplift" causes the ceiling to move upward. Fasteners too close to the edge of the ceiling in such structures will often result in cracked joints.
8-12" better - especially with roof trusses, but fine for any ceiling
