This is a consequence of the increasing number of keys. It makes very good sense to copy a DB_CONFIG file of BDB tunables to each of DB and PTree after [fast]build and pbuild respectively.
The SKS maintainers are still working on the baseset of tuning values, but DB_CONFIG is now included in the main source tarball, so updates should be less of a headache. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
