File System
 

Hi
I am a little bit apprehensive whether this is a place to ask this query or not --Though I am new to this site inspite of working more than two years in software industry ------can anyone inform me is there any thread or forum that is dedicated to File system . Thanks in advance

Dedicated to WHAT about "file system"?? What do you need to know? What questions do you have?

We need more information, are you having a problem with one, need to know what type to use, or some other question about it.

I have some basic questions --like --when ever any new file system is mounted is it essential that it should be mounted within root file system.

So your question is about the Linux FHS (Filesystem Hierarchy Standard) then..

I assume you mean the basic structure starting with "/" (also called "root", but "root" is used in many ways.)

Yes, the kernel is told at boot time what partition/filesystem to use as the starting point (root). Anything that is connected later has to be related to this. There is however a function called "chroot" (change root) which allows you to change it.
