+### Workaround for busybox in /sbin:
+Some kernel include busybox in the ramdisk, in ``/sbin/busybox``. This is mostly done to accommodate busybox calls in recovery mode. In the default setup of Terminal Emulator, ``/sbin`` is given preference over ``/system/bin`` and ``/system/xbin``. Thus, Online Nandroid uses ``/sbin/busybox`` over any other busybox installations. The issue arises when the busybox binary in ``/sbin/busybox`` is out of date. This sometimes causes undesired affects for Online Nandroid. To overcome this situation, you can use the below command line  flag.
+```shell
+onandroid -t
+OR
+onandroid --sbin-last
+```
+
