* The fd holder in s6 seem unable to retain its state over restart,
While I'm at it, here's the procedure to safely restart a s6-fdholder-daemon: 1. Start up another, temporary, s6-fdholder-daemon 2. s6-fdholder-transferdump the whole state from your main daemon to the tmp 3. Restart the main daemon 4. s6-fdholder-transferdump in the other direction 5. Kill your tmp daemon. This can easily be automated, and you could even trap SIGTERM in your main s6-fdholder-daemon service to call such a script and perform restarts without state loss. -- Laurent
