This is even broken if doing a FRESH installation using debconf
preseeding.
Before portmap is installed the debconf setting looks like:
# dpkg --list portmap
[...]
un portmap <none>
(no description available)
# grep -A1 portmap/loopback /var/cache/debconf/config.dat
Name: portmap/loopback
Template: portmap/loopback
Value: false
Installing portmap in non-interactive mode then:
# dpkg --list portmap
[...]
ii portmap 6.0.0-1
RPC port mapper
Now the configuration is NOT what debconf preseeding told it to be:
# grep -A1 portmap/loopback /var/cache/debconf/config.dat
Name: portmap/loopback
Template: portmap/loopback
Value: true
# cat /etc/default/portmap
# Portmap configuration file
#
# Note: if you manually edit this configuration file,
# portmap configuration scripts will avoid modifying it
# (for example, by running 'dpkg-reconfigure portmap').
# If you want portmap to listen only to the loopback
# interface, uncomment the following line (it will be
# uncommented automatically if you configure this
# through debconf).
OPTIONS="-i 127.0.0.1"
Looking at postinst script:
if [ "$1" = "configure" ] && [ -n "$2" ] && dpkg --compare-versions "$2" lt
"5-7ubuntu2"; then
db_set portmap/loopback true
fi
... this won't work:
# dpkg --compare-versions 6.0.0-1 lt "5-7ubuntu2" && echo ok || echo error
error
So you're overriding the configuration with each
installation/upgrade process (at least for >=6.x versions).
