default layout skips the swap, tmp, usr, var all that other stuff. are those all necessary
That depends on what purpose the server is used for. By default all will be a part of `/`. In case I need to have a layout, I would prefer `/tmp`, `/var` to be on different partitions. In case your `/tmp` is part of the `/`, if that gets filled up, you server will crash, which you don't want to happen.In case your `/var` gets fulled, most of the services will stop working.
