For some mysterious reason dnf now exists in an update when I run in the 
fsm_file_prepare hook. After that, when telling dnf to install a package, 
it enumerates all kinds of locks that it unlocks. Do you know what may be 
the cause for this ?

Following these issues, I would like to try to meve it to the 
fsm_file_post hook.
