OK.  I would suggest removing these from nssdatabases-defaults for
the time being if this is causing problems, as a workaround.

I wonder if (for buildd chroots) we should be running dpkg with
--force-confnew to unconditionally force replacement with new
conffiles?  If this is configurable via APT such as
Dpkg::Options::force=--force-confnew then maybe we should be
setting this by default (this applies more generally than just
this specific case).

We could remove these files from nssdatabases-defaults to avoid
this issue.  However, the idea is that all the NSS databases
are "slaved" to the host and automated updating is wanted in
almost all cases.

We were considering creating a separate set of buildd defaults,
which would still allow the current default behaviour on non-
buildd systems, while allowing the defaults to be restricted
on buildd setups.

Does anyone else have any further comments?


Thanks for reporting this!
