Description Michael Tremer 2026-05-15 09:39:42 UTC

We need to engineer a replacement to the Unbound DHCP Leases Bridge.

Since that has always been an utter ball ache, we will need to replace this with another solution which currently is unknown.

I have pushed a couple of changes that are supposed to implement this now. Instead of parsing the lease file, the DHCP server will call a script to store all leases in a sqlite3 database which will be queried by kresd through a custom policy module:

The module uses a simple print() statement for logging which will need to be replaced by proper logging as soon as it has been verified that this approach is workable.
