cyrus-imapd-2.2 and libdb

There are two issues here:
1) The BDB version to be used in future cyrus-imapd packages is yet
undecided because there have been issues with various versions
between 4.2 and 4.6. OpenLDAP and Cyrus IMAPd & SASL are the
software packages that trigger the most BDB bugs. But we tend
to follow the OpenLDAP maintainers on their decision (whichever it
2) If you upload an NMU, you must make sure that the existing BDB
databases are not simply discarded, but are converted to whatever
you are intending to use. Make sure your upgrading scripts also
work with non-standard configurations.
The second issue (and a serious lack in time of the old pack of
maintainers - those you originally Cc'd: benjamin, hmh, ondrej and me)
is the main reason why there isn't already a newer package of
cyrus-imapd which actually uses a newer BDB version. We maintainers are
quite sure that we do not want a package update to break any previously
working installation on the users site, so whatever the update does, it
must make sure that it somehow parses /etc/imapd.conf, checking the *_db
settings (falling back to the defaults if one isn't found) for any
"berkeley" entries, and upgrades those if there are any. Note that the
user might also have changed some paths (actually, I think that it is
more common to do so than not) to the databases.
The following databases (check pathes on an actual installation) are
berkeleydb by default:
(where the last one might actually be purged on upgrades and re-created)
Note also that some of the databases are per user, some per partition...
As you see, the upgrade is far from being trivial. So help is greatly
appreciated, but simply using the Ubuntu patch(es) and rebuilding will
not do it.
