I am told that it’s documented under “CONFORMANCE” here: https://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man2/rename.2.html#//apple_ref/doc/man/2/rename The restriction on renaming a directory whose permissions disallow writing is based on the fact that UFS directories contain a ".." entry. If renaming a directory would move it to another parent directory, this entry needs to be changed. Thanks, Ludo’.
