Root category homepage possible solution

[versedi]

Hello,

Is it possible to trigger filterurls also on homepage that displays all products from root category?
It isn't working with home set as CMS Page with layout update XML because it cant reference current category then.

<reference name="root">
    <action method="setTemplate"><template>page/2columns-left.phtml</template></action>
</reference>
<reference name="content">     
        <action method="setCategoryId"><category_id>2</category_id></action>         
        <block type="catalog/product_list"  name="product_list" template="catalog/product/list.phtml">        
            <block type="catalog/layer_view" name="catalog.layered"  template="catalog/layer/view_horizontal.phtml" before="product_list_toolbar">
            </block> 
            <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml" before="catalog.layered">
                <block type="page/html_pager" name="product_list_toolbar_pager"/>         
            </block>         
            <action method="setCategoryId"><category_id>2</category_id></action>         
            <action method="setToolbarBlockName"><name>product_list_toolbar</name></action>     
        </block> 
</reference> 

How would you solve it? Maybe there's a more proper way for all products home page with which filter urls would also work?
Have a nice day.

P.S. Working solution that I've found is to setup a new non-root category and apply it to all products - then use that category for homepage.
