Can you show us the relink.log when it fails?
It does not fail since a while. I think, the problem is the following: I booted and rebooted immediately, and tested doing that again, but the script for relinking kernel runs in underground and takes a lot of time. I wondered why I got the message at the end, perhaps because I shuted down before the script ended. I would preffer to run the script for relinking kernel from time to time manually, and not run it at boot time. The same for reordering libraries. I also avoid to start deamons at boot time that I not need at the moment. See it as the opposite of the systemd ideology. Rodrigo.
