   Thanks a lot for this detailed explanation about how all this is (was)   
   supposed to work.   
      
   I'm doing a retitle to better reflect what we know about this failure.   
   (Based on your explanations, if the autodetection worked as designed   
   then there would be nothing wrong in calling "3cpio" as "3cpio").   
      
      
   This looks like some kind of race condition to me, similar to this one   
   which happened some time ago in the "sumo" package. This is the   
   message where Niels diagnosed the problem and solved the mystery:   
      
   https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1082135#19   
      
   With the sumo package in mind, I looked at the dracut script   
   to see if there was any occurrence of "&", and found that   
   there is a "parallel mode".   
      
   Can you tell if this parallel mode is the default, and if not, what   
   other reasons for a race condition can be?   
      
      
   I would be willing to build linux-signed-amd64 a lot of times using a   
   modified dracut package with whatever debug changes we could add to   
   see what's going on (even if they are simple "echo foo"), so I'm   
   open for suggestions about those potential changes.   
      
   Thanks.
