<div class="moz-cite-prefix">Hi Martin,<br>
<br>
I think this is the same problem we discussed before.<br>
The thread is "busybox: fix the on-target upgrade problem".<br>
<br>
The problem roots in opkg's update-alternatives.
<br>
At that time, I made a patch to fix this problem.<br>
I didn't send it out because I then found some other problems with
update-alternatives in OE/Yocto.<br>
And I filed a bug to track these issues. I wanted to fix them all
in one patchset.<br>

<br>
Best Regards,<br>

should base_bindir be used for ALTERNATIVE_LINK_NAME and bindir for TARGET?
