Legato legacy App - Directory permissions

I tried on WP750x.
I put the test script here:

root@swi-mdm9x15:/tmp# cat test.sh
echo > /tmp/123.txt

After that I run a unsandboxed legato application:

#include “legato.h”

COMPONENT_INIT
{
system(“/tmp/test.sh”);
LE_INFO(“Hello, world.”);
}

I can create /tmp/123.txt.
