Live CD

Live CD,an operating system on CD. I was really amazed, my eyes dazzled, when i saw that for a first time.

Later i found it as real easy to get into details of live cd.

So whats the difference between a normal linux hd install and live cd.
The Filesystem and the booting options. Really, the invention of UnionFS made a livecd possible, it made a unreadable parts readable..... Yeah hell very simple , Hell they made a soft link of the file on the ram. I made it look simple whereas infact its not, we need a detailed understanding of the filesystem.

But the fact is filesystem which looks so simple , small logical improvement made a big deal out of it.
