             Once a provider is selected, BitBake resolves all the dependencies for  
             the target. 
             In the case of <filename>core-image-sato</filename>, it would lead to 
-            <filename>task-base.bb</filename>,  
+            <filename>packagegroup-base.bb</filename>,  
             which in turn leads to packages like <filename>Contacts</filename>, 
             <filename>Dates</filename> and <filename>BusyBox</filename>.
             These packages in turn depend on <filename>eglibc</filename> and the toolchain.
