Package conflicts prevent building (findfs|tune2fs, logger|busybox)

Hi,

I added some packages to my image but selected incompatible packages:

check_data_file_clashes: Package findfs wants to install ... findfs
        But that file is already provided by package  * tune2fs
check_data_file_clashes: Package logger wants to install ... logger
        But that file is already provided by package  * busybox
package/Makefile:60: recipe for target 'package/install' failed

Is it expected? I think busybox is required, so logger could not be installed anytime, so why having it at all?
