6 # Abort if any command returns an error value
9 # This script is called as the last step of the installation of the
10 # package. All the package's files are in place, dpkg has already done
11 # its automatic conffile handling, and all the packages we depend of
12 # are already fully installed and configured.
16 # Configure this package. If the package must prompt the user for
17 # information, do it here.
20 #ln -s /usr/sbin/citmail /usr/sbin/sendmail
22 chown root:citadel /usr/sbin/sendmail
23 chmod 04755 /usr/sbin/sendmail
24 ### We could also do this on the fly. The following is from Tore
27 #. /usr/share/debconf/confmodule
29 ### find out what the user answered.
30 # db_get foo/run_on_boot
34 ### safely create a temporary file to generate our suggested
35 ### configuration file.
37 # cat << _eof > $tempfile
38 ### Configuration file for Foo.
40 ### this was answered by you, the user in a debconf dialogue
41 # RUNONBOOT=$run_on_boot
43 ### this was not, as it has a sane default value.
48 ### Note that some versions of debconf do not release stdin, so
49 ### the following invocation of ucf may not work, since the stdin
50 ### is never coneected to ucfr.
52 ### now, invoke ucf, which will take care of the rest, and ask
53 ### the user if he wants to update his file, if it is modified.
54 #ucf $tempfile /etc/foo.conf
56 ### done! now we'll just clear up our cruft.
60 #### There are three sub-cases:
61 ###if test "${2+set}" != set; then
62 ### # We're being installed by an ancient dpkg which doesn't remember
63 ### # which version was most recently configured, or even whether
64 ### # there is a most recently configured version.
67 ###elif test -z "$2" -o "$2" = "<unknown>"; then
68 ### # The package has not ever been configured on this system, or was
69 ### # purged since it was last configured.
73 ### # Version $2 is the most recently configured version of this
80 # Back out of an attempt to upgrade this package FROM THIS VERSION
81 # to version $2. Undo the effects of "prerm upgrade $2".
86 ###if test "$2" != in-favour; then
87 ### echo "$0: undocumented call to \`postinst $*'" 1>&2
90 #### Back out of an attempt to remove this package, which was due to
91 #### a conflict with package $3 (version $4). Undo the effects of
92 #### "prerm remove in-favour $3 $4".
97 ###if test "$2" != in-favour -o "$5" != removing; then
98 ### echo "$0: undocumented call to \`postinst $*'" 1>&2
101 #### Back out of an attempt to deconfigure this package, which was
102 #### due to package $6 (version $7) which we depend on being removed
103 #### to make way for package $3 (version $4). Undo the effects of
104 #### "prerm deconfigure in-favour $3 $4 removing $6 $7".
