For some reason, they say its to be able to recover from desasters, some Linux users partition drives rather stupid. This layout is created by the Distribution CD.

The problem is a few months down the line the / {root} partition fills up and voila big mess!
To fix the problem takes an anormous amount of time and Knowledge.
PPL keep it simple, Make backup, and Make One Pasrtition so that isf something Fill up its NOT the tmp directory or the root one!
If the Whole disk fills up then ok, the chances for this is somewhat smaller than the cylinders allocated by the Distribution.!!!
It happened 3x in RL running environments it will happen again. PPL think about this find a nother solution if you absolutely HAVE to partition is pieces!
