Description Stefan Gohmann univentionstaff 2016-02-12 06:37:43 CET
Currently, we see some systems with the same UUID. This could happen if the setup failed.

Another issue seems to be that the UUID is created two times during a normal installation first in the updater postinst and later in the appliance-hook.

I think we should remove the UUID creation in updater.postinst and we should move the UUID creation in setup-join to an earlier point.

Another possibility:
We create an init script which generates the UUID if some system identification points have been changed (MAC, HDD, RAM, CPU, ...). This means if the hardware has been changed, the UUID would change. That would be OK and we could also save the UUID history.
