Suite à une simple mise à jour de sécurité, de grosses difficultés à redémarrer coon.
Quelques traces :

Pour débloquer la situation, il a fallu annuler des modifs de configuration de minetest dans firehol.conf alors que ce dernier ne présente absolument aucune source potentielle d'anomalie.

Commentaire de PoluX sur #4599 :
Après une longue investigation avec Christian, on a tiqué sur :
Jul 15 00:01:20 coon delayed_fw_reload[1616]: ERROR: FireHOL is already running. Exiting...
On soupçonne une race condition qui apparait du fait que les regles iptables deviennent nombreuses (4000).
En regardant la conf systemd de libvirtd sur coon on tombe sur :
Drop-In: /etc/systemd/system/libvirtd.service.d
└─override.conf
[...]
Process: 1441 ExecStartPost=/usr/local/bin/delayed_fw_reload (code=exited, status=0/SUCCESS)
Ça ressemble à une cochonceté oubliée, datant des premiers jours du cluster. Depuis, les hooks network on rendu ça inutiles.
Par ailleurs le code impliqué est plus que naïf.
# cat /usr/local/bin/delayed_fw_reload
#!/bin/bash
sleep 10 && firehol start
Je dégage tout ça de coon. Maine en est exempt.

Le test de redémarrage avec les modifs firehost ré-intégrées donne un résultat nominal. Donc nous validons que ça venait de ça \o/
