Package: dovecot-common Version: 1:2.0.13-1 Severity: normal Hi there!
After having upgraded to the latest dovecot-common package in unstable,
I found that some configuration files are leftover:
=====

Apart from doveconf.conf.ucf-old (which is the old monolithic
configuration file), all the others have been automatically created
at dovecot-common installation:

However, these files are not listed as dpkg's conffiles, but they are
created in postinst and removed on purge (checked on a squeeze system,
given that my sid has already been upgraded):

Now, if these files are still useful, why is there a new
dovecot-sql.conf.ext, which minimally differs from the old
dovecot-sql.conf?

In general, however, it seems that we have three different bugs, here:
1) triplicate "example" files
a. /usr/share/doc/dovecot-common/example-config/
(which is *NOT* /usr/share/doc/dovecot/example-config/ as
/etc/dovecot/README contains)
b. /usr/share/dovecot/
c. /etc/dovecot/
2) useless extension for "example" files, given that .ext does not mean
anything at all and it is counter-intuitive, if it means "example".
I would also question the usefulness of such files (both the old
-example.conf and the new .conf.ext), given that if they are examples
they should stay away from /etc.
3) leftover example files after upgrade
a. dovecot.conf.bak
b. dovecot-db-example.conf (same as dovecot-db.conf.ext)
c. dovecot-dict-sql-example.conf (same as dovecot-dict-sql.conf.ext)
d. dovecot-ldap.conf
e. dovecot-sql.conf (one useful difference with dovecot-sql.conf.ext)
Please install in /etc only what is really necessary.
Thx, bye,
Gismo / Luca
