CyanogenMod comes with inbuilt busybox? Does CyanogenMod 11 come with busybox pre-installed, or does it need to be installed separately?
yes cyanogenmod always provides a busybox installation.

The repo manifest file contains an entry as following:

&lt;project path="external/busybox" name="CyanogenMod/android_external_busybox"/&gt;
