I am using following distribution for raspberry pi.

FOR rpi It is recommended to use >2GB card.
Also when i install it on my memory card size of root file system is about 1.4GB. But dont you think it is too much size just for an root filesystem in EMBEDDED SYSTEM.
Is it possible for RPI to make a linux distribution with root file system with small size ?
Because most of the embedded system do not have this much memory.
like carambola have 8mb Flash & 32 MB RAM.

In this case carambola root filesystem (OPEN wrt) will fit in 8MB flash. How is it possible ?
Raspbian is a full on general purpose operating system, with the ability to run X windows, create a development environment, watch movies, play games, etc.
It also includes support for a great many devices you might want to connect via USB, such as networking devices, webcams, keyboards, mice, etc.
Many embedded systems are purpose built, with no options for adding/removing devices, nor options for running arbitrary programs. OpenWRT is a routing platform running on typical router hardware, and as such, can be MUCH smaller.
