Ok, my guess about this was bad, "set -e" does not prevent the script
to go on, I'll have to revise my shell scripting skills :
script -c 'debconf sh -x /var/lib/dpkg/info/nbd-client.postinst configure
1:2.8.7-4'

Nevertheless, this did not create anything in /etc, so
I investigated further.
I found it weird to see this in my debconf config.dat, whereas I've
chosen "1" as the number of connections to configure :
Name: nbd-client/number
Template: nbd-client/number
Value: 0
Owners: nbd-client
Flags: seen
After I dpkg-reconfigured nbd-client, and chose "1" again, the debconf value
of nbd-client/number is now 1, and /etc/nbd-client was
successfully created.
I then re-did this :
script -c 'debconf sh -x /var/lib/dpkg/info/nbd-client.postinst configure
1:2.8.7-4'

So it really seems my guess was wrong, this postinst script does work.
Another test, then :
$ sudo dpkg --purge nbd-client ; sudo rm /etc/nbd-client
==> no more debconf data about nbd-client, as expected.
Then I apt-get installed it, answered debconf questions the same way
as usual, keeping an eye on /var/cache/debconf/config.dat all along
the installation, and :
- just after I answer debconf questions, config.dat contains correct
data (nbd-client/number is 1)
- at some point in the install process, nbd-client/number gets
a (wrong) value of 0...
- to end with, /etc/nbd-client is not created.
This seemed pretty strange behaviour, and I was thinking of a weird
apt/dpkg interaction issue, so I had a look to my apt config ; the
only item related to such an issue was in
/etc/apt/apt.conf.d/70debconf :
// Pre-configure all packages with debconf before they are installed.
// If you don't like it, comment it out.
DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt || true";};
I commented this out, purged again, apt-get installed, and...
everything worked perfectly !
I have this setting enabled on all my etch boxes, and neither me nor
my Changelogs remember having tweaked it, so I guess this is standard,
isn't it ?
