 I had a problem when upgrading to to Kea 2.6.0 that stopped kea-dhcp4 operating with an error ''file: /etc/kea/kea-dhcp4.conf, reason: subnet configuration failed: missing parameter ‘id’''.  The error also reported the configuration line where the missing parameter was expected.  Adding the missing parameter to the file as per Kea docs [[https://kea.readthedocs.io/en/kea-2.6.0/arm/dhcp4-srv.html#ipv4-subnet-identifier|ipv4-subnet-identifier]] resolved this error.  Apparently this parameter was auto assigned in earlier versions of Kea, if not manually assigned in configuration file.  In Kea version 2.6.0 manual assignment became mandatory, see [[https://kb.isc.org/docs/changes-to-be-aware-of-when-migrating-to-kea-2-6-0|Changes to Be Aware of When Migrating to Kea 2.6.0]].++++
+++++Upgrade problems from Kea 2.6.2 to 2.6.3, yet again broken or perhaps enforced configuration backwards compatibility, TL;DR;|
+The socket files **must** now be in ''/run/kea'' and directory permission must be set to 750.
+I previously used a general docker volume director directive to place all my configuration files into /app and then configured from there as required.

+    "output": "/var/log/kea/kea-dhcp4.log",
+Symlinking did not seem to work:   /bin/ln -sf /app/log/ /var/log/kea , so I created a specific docker volume to the log file and this did work,  - '/mnt/docker_store/kea/.config/log:/var/log/kea'.
