# This script is called as the last step of the installation of the
# package. All the package's files are in place, dpkg has already done
# its automatic conffile handling, and all the packages we depend of
# are already fully installed and configured.

# against being run in the abort-* cases.

# Tell ucf that the file in /usr/share/foo is the latest
# maintainer version, and let it handle how to manage the real
# confuguration file in /etc. This is how a static configuration
# file can be handled:
ucf /usr/share/foo/configuration /etc/foo.conf
ucfr foo /etc/foo.conf
### We could also do this on the fly. The following is from Tore
### Anderson:
#. /usr/share/debconf/confmodule
### find out what the user answered.
# db_get foo/run_on_boot
# run_on_boot=$RET
# db_stop
### safely create a temporary file to generate our suggested
### configuration file.
# tempfile=`tempfile`
# cat << _eof > $tempfile
### Configuration file for Foo.
### this was answered by you, the user in a debconf dialogue
# RUNONBOOT=$run_on_boot
### this was not, as it has a sane default value.
# COLOUROFSKY=blue
#_eof
### Note that some versions of debconf do not release stdin, so
### the following invocation of ucf may not work, since the stdin
### is never coneected to ucfr.
### now, invoke ucf, which will take care of the rest, and ask
### the user if he wants to update his file, if it is modified.
#ucf $tempfile /etc/foo.conf
### done! now we'll just clear up our cruft.
