Package: ucf
Version: 3.0016
Severity: normal
Dovecot is a package whose postinst does not use debconf directly but
it calls "ucf --three-way ..."
Currently, the --three-way option is not honored at all.
Looking at the processus during the installation, I see:

You can see how ucf, called from within debconf, does not have the --three-way
switch anymore.
I did not verify, but I suspect that:
1) ucf calls getopts to manage its options (it needs it to check for
--debconf-ok at least)
getopts (and "eval set -- ...") manage and remove all options from "$@"
2) debconf is not running so it is started
=> debconf restart the script with "$@" options (so --three-way is lost)
3) ucf is run inside debconf without the --three-way option
