在源包的debian/package.postinst中添加自定义步骤？

Question

我有一个包，其中包含一个自动生成的debian/package.postinst.debhelper文件。当我将自己的代码放入debian/package.postinst文件中时，自动生成的文件不再被包含在生成的二进制文件中。

我如何在生成的包中添加自定义代码到postinst文件，而不阻止使用自动生成的代码？

您的postinst脚本应该包含一个#DEBHELPER#标记，如果您使用了任何可能修改它的debhelper命令。在生成的脚本中，它将被自动生成的内容替换。请参阅manpage for the dh_installdeb command 。

例如：

#!/bin/sh
# postinst script for webpy-example
#
# see: dh_installdeb(1)

set -e

# summary of how this script can be called:
#        * <postinst> `configure' <most-recently-configured-version>
#        * <old-postinst> `abort-upgrade' <new version>
#        * <conflictor's-postinst> `abort-remove' `in-favour' <package>
#          <new-version>
#        * <postinst> `abort-remove'
#        * <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

# source debconf library
. /usr/share/debconf/confmodule

# Source dbconfig-common functions
if [ -f /usr/share/dbconfig-common/dpkg/postinst.pgsql  ]; then
  . /usr/share/dbconfig-common/dpkg/postinst.pgsql
fi

case "$1" in

  configure)
    # Set up our config for apache
    /bin/cp /usr/share/webpy-example/postinstall/webpy-config /etc/apache2/conf.d/
    /usr/sbin/a2enmod wsgi
    /usr/sbin/a2enmod rewrite
    /etc/init.d/apache2 reload

    # set up database
    dbc_pgsql_createdb_encoding="UTF8"
    dbc_generate_include=template:/usr/share/webpy-example/lib/credentials.py

    dbc_generate_include_owner="root:www-data"
    dbc_generate_include_perms="0660"
    dbc_go webpy-example $@ || true

  abort-upgrade|abort-remove|abort-deconfigure)
    exit 0
  ;;

    echo "postinst called with unknown argument \`$1'" >&2
    exit 1

esac

# dh_installdeb will replace this with shell code automatically
