				// There was a Capsicum-related regression in FreeBSD renameat,
				// which affects certain cases independent of Capsicum or capability mode
				//
				// added to test the renameat syscall for the case that
				// - the "to" file already exists
				// - the "to" file is specified by an absolute path
				// - the "to" file descriptor is used
				// (this descriptor should be ignored if absolute path is provided)
				//
				// details at: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222258
