Description Stefan Schantl 2026-05-23 13:10:26 UTC 
When trying the latest and first knot-resolver ISO image i stumbled across the following issue:

May 23 14:52:00 ipfire supervisord: captured stdio output from kresd1[6841]: leases: Failed to open /var/lib/knot-resolver/dhcp-leases.db

This is correct, and somewhat intentional.

At the moment, I am not sure when this database should be created. At build time so it is always there?
Comment 3 Adam Gibbons 2026-05-28 14:09:36 UTC 
In my test case, /var/lib/knot-resolver/leases.db did exist, but it was owned root:root 0644 while /var/lib/knot-resolver was root:root 0755. Knot Resolver could not use the DB correctly and leases.lua produced sql_fwd/sql_rev nil errors.

After chowning /var/lib/knot-resolver and leases.db to knot-resolver:knot-resolver, DHCP lease A/PTR lookups worked and remained working after reboot.

This may be the same root cause as bug 13983 rather than a pure “file missing” case.
