Is there any FS that have dynamic allocation?

	On one partition can reside a number of FSs and using only needed space? this
would be really cute - HD behaves just like RAM.

	Some FSs on partition just like number files on FS.
	In other words "File Systems' System".

	google and altavista both show nothing...

PS Interesting like academic task. Hm. Will invistigate.
