The aim is to reduce the size of the image further so that it can fit in 
lesser memory devices like am62l(128MiB).
Since we do not require login support for the usecase of just probing 
modules I removed the login manager here.
Similarly initramfs-udev will handle what we aim with this image instead 
of having a runtime dev manager separately.

The change results in shrinking the image from 90MBs(20MBs compressed) 
to about 25MB's (6-7 MBs compressed).
