Package: xserver-xfree86
Version: 4.2.1-3
Summary:
Answering "no" to move_existing_nondebconf_config doesn't stop dexconf
from running, and the question is repeatedly asked on every
reinstall/upgrade of xserver-xfree86.
This should be pretty easy to reproduce; replace /etc/X11/XF86Config-4
with an empty file, dpkg-reconfigure xserver-xfree86, say "Yes" to
"Manage config with debconf" and "No" to "Replace existing config
file"; postinst will either write the file or fail (depending on what
random values happened to be in the debconf database), and "Replace
existing config file" will be asked again on the next
installation.
(The workaround is fairly obvious; dpkg-reconfigure xserver-xfree86
and say "no" to the first question)
The basic problem is that, in the config script, if the user replies
"no" to move_existing_nondebconf_config then the script aborts
immediately. However, this does not affect the postinst's behaviour;
it tries to create the file anyway.
My inclination is that config should db_set manage_config_with_debconf
to false if move_existing_nondebconf_config is false. Also, postinst
probably needs to check both values and do something appropriate in
the yes/no case.
FWIW, the output of=20
/usr/share/debconf/frontend sh -x /var/lib/dpkg/info/xserver-xfree86.postin=
st configure
and
debconf-show xserver-xfree86
is attached, in the broken state.

xfree86 (4.2.1-11) unstable; urgency=3Dmedium
* The following configuration files use a new, MD5-checksum-based method =
of
management:
- /etc/X11/X
- /etc/X11/XF86Config-4
- /etc/X11/Xwrapper.config
This new method attempts to detect changes to these files, and if they =
are
modified by the user, the files will be ignored by the packaging system
henceforth. The debconf region markers (e.g. "### BEGIN DEBCONF SECTIO=
N")
formerly used in Xwrapper.config and XF86Config-4 are no longer used, a=
re
disregarded if present, and will not be newly written.
The debconf templates in the xserver-common, xserver-xfree86, and
xserver-xfree86-dbg packages (the latter shares all of its templates wi=
th
xserver-xfree86) having to do with whether or not files on the disk sho=
uld
be overwritten have been removed, and are unregistered in the new
packages' pre-installation scripts.
In the event that you have customized these configuration files, and ha=
ve
neglected both to correct debconf's notion of whether it should manage
those files, and (in the case of Xwrapper.config and XF86Config-4) have
not removed the "debconf region markers" before upgrading to xfree86
4.2.1-10 or later, backups are made and stored in the same directory, w=
ith
the suffix ".dpkg-old".
See the Debian X FAQ at <http://people.debian.org/~branden/xsf/FAQ> or =
in
the file /usr/share/doc/xfree86-common/FAQ.gz after this upgrade is
complete for more information on the Debian XFree86 packages' new method
of handling these configuration files.
