If I want to install bash together with busybox ash, yocto does not consider the ALTERNATIVE_PRIORITY in each case (e.g. if bash is installed before busybox). The problem is that do_install of busybox creates a link to busybox.nosuid. Is there a reason for that? Shouldn't update-alternatives create that link for us? There is already a patch available that targets this problem (467b19efbaa9c0cb04d2665e8cd9a0919849a5ed ) but it only works if ash is completely disabled in the busybox config.

I can confirm that this is indeed a problem. And we need to fix this.
I think the reason for this line is mainly to make 'busybox' provide 
'/bin/sh' so that do_rootfs would succeed.
