it says can't become group root because...
if (setuid(0) != 0)
{
E_UTIL_SUID_ERR("Unable to assume root user privileges\n");
return 37;
}
if (setgid(0) != 0)
{
E_UTIL_SUID_ERR("Unable to assume root group privileges\n");
return 38;
}
that is literally the code. setting group to 0 fails. so sayeth the system.
