It'd be better to call system(3) once with the full path of the  
script, also check the return status of the syscall:

int rc;
switch ((rc = system("/mnt/flash/cdBluez-start")))
{
     case -1:
         warn("waitpid or fork failure: %s", strerror(errno));
         break;
     case 0:  /* this should be ok */
         break;
     case 127:
         warn("shell execution failed");
         break;
     default:
         warn("cdBluez-start returned with status %d", rc);
         break;
}

Otherwise, since system(3) spawns a different shell each time it is  
invoked, the first "cd /mnt/flash" is lost when the "./cdBluez-start"  
is called.

the unexpected "(" is an error message coming from the bourne shell,  
it depends on your script.

Hope it helps, t.
