kea-0/kea-1 crash-loop on startup (deployed via argocd-apps dhcp-system). kea 2.6.5 restricts control/HA unix socket paths to its compiled runstatedir and rejects any other path by exact string match, even though /var/run symlinks to /run:

FATAL DCTL_CONFIG_FILE_LOAD_FAIL Control-agent reason: invalid path specified: '/run/kea', supported path is '/var/run/kea'

The operator rendered all sockets under /run/kea, so both kea-dhcp4 and kea-ctrl-agent fail config load.

  • Point RunDir at /var/run/kea so every derived config/socket path matches kea's permitted directory.
  • Pre-create /var/run/kea in the kea workload image.
  • Add tests asserting the rendered dhcp4 + ctrl-agent socket paths live under /var/run/kea.

Needs a v0.1.1 release afterwards so argocd-apps can bump the operator image.

Kea 2.6.5 restricts control/HA unix socket paths to its compiled
runstatedir and rejects any other path by exact string match
("invalid path specified: '/run/kea', supported path is '/var/run/kea'"),
even though /var/run is a symlink to /run. The operator rendered sockets
under /run/kea, so kea-dhcp4 and kea-ctrl-agent crash-looped on startup.

- Point RunDir at /var/run/kea so all derived config/socket paths match.
- Pre-create /var/run/kea in the kea image.
- Assert rendered socket paths live under /var/run/kea.
