>Description:
On an upgrade from NetBSD-10.1 (and possibly NetBSD-11.0_BETA), blocklistd generates the following error (repeatedly):

blocklistd[1084]: Key size mismatch 296 != 288

This can be stopped by stopping blocklistd, removing /var/db/blocklistd.db, and restarting blocklistd.

Note that although I compiled the system myself (see uname above), there is nothing different that relates to blocklistd; thus, this should also be the case for upgrading stock systems.
>How-To-Repeat:
(i) Install an older version of NetBSD with blocklistd running, and (ii) upgrade (i.e., not reinstall) to 11.0 and start blocklistd again.

Responsible-Changed-By: riastradh@NetBSD.org
Responsible-Changed-When: Wed, 05 Aug 2026 23:32:45 +0000
Responsible-Changed-Why:
over to blocklistd maintainer

If there are schema changes, we should really have a path to update
from one schema to another, and postinstall should be able to do this
or at least warn about it automatically.
