# 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.
# summary of how this script can be called:
#        * <postinst> `configure' <most-recently-configured-version>
#        * <old-postinst> `abort-upgrade' <new version>
#        * <old-postinst> abort-remove  # if prerm fails during removal
#        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
#          <new-version>
#        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
#          <failed-install-package> <version> `removing'
#          <conflicting-package> <version>
# for details, see http://www.debian.org/doc/debian-policy/ or
# the debian-policy package
#
# quoting from the policy:
#     Any necessary prompting should almost always be confined to the
#     post-installation script, and should be protected with a conditional
#     so that unnecessary prompting doesn't happen if a package's
#     installation fails and the `postinst' is called with `abort-upgrade',
#     `abort-remove' or `abort-deconfigure'.

# The following idempotent stuff doesn't generally need protecting
# against being run in the abort-* cases.

    # Tell ucf that the file in /usr/share/foo is the latest

    ### 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.
    #rm -f $tempfile
