Quote from: tkreagan on June 15, 2026, 09:25:12 PMHi all — I've been following this topic and wanted to share something I built that I think addresses exactly this problem.
**os-kea-ubnd-ddns** is an OPNsense plugin that bridges Kea DHCP → Unbound DNS directly, without Bind. It runs a lightweight RFC 2136 stub listener that receives DNS UPDATE packets from `kea-dhcp-ddns` and applies them to Unbound via `unbound-control` — so you get real-time hostname registration when a lease is issued - no zone files, no journal corruption, no `.jnl` cleanup.

Quote from: nero355 on Today at 02:01:43 PMIn theory ZFS should never use more than 50% of that IIRC so you should have nothing to worry about despite these values.
