|

|

Cleanup: rewrote the Postfix installation procedure again.
|
||||
It is now separated into 1) a primary installation script
|
||||
(postfix-install) that installs files locally or that builds
|
||||
a package for distribution and that stores file owner and
|
||||
permission information in /etc/postfix/post-files, and 2)
|
||||
a post-installation script (/etc/postfix/post-install) that
|
||||
creates missing directories, that sets file/directory
|
||||
ownership and permissions, and that upgrades existing
|
||||
configuration files if necessary.
|
||||
|
||||

|
||||
|
||||
Workaround: AIX null read() return on an empty but open
|
||||
non-blocking pipe. File: master/master_flow.c. Report:

# Postfix post-installation script
|
||||
# SYNOPSIS
|
||||
# post-install [options] config_directory
|
||||
# DESCRIPTION
|
||||
# The post-install script performs the finishing touch of a Postfix
|
||||
# installation, after the executable programs and configuration
|
||||
# files are installed. Usage is one of the following:
|
||||
# .IP o
|
||||
# While installing Postfix from source code on the local machine, the
|
||||
# script is run by the postfix-install script to update selected file
|
||||
# or directory permissions and to update selected configuration files.
|
||||
# .IP o
|
||||
# While installing Postfix from a pre-built package, the script is run
|
||||
# by the package management procedure to set all file or directory
|
||||
# permissions and to update existing Postfix configuration files.
|
||||
# .IP o
|
||||
# At Postfix start-up time, the script is run from "postfix check" to
|
||||
# create missing queue directories.
|
||||
# .PP
|
||||
# Arguments
|
||||
# .IP -create
|
||||
# Create missing queue directories with ownerships and permissions
|
||||
# according to the contents of $config_directory/postfix-files.
|
||||
#
|
||||
# This is required at Postfix start-up time.
|
||||
# .IP -set-permissions
|
||||
# Set all file/directory ownerships and permissions according to the
|
||||
# contents of $config_directory/postfix-files. Implies -create.
|
||||
#
|
||||
# This is required when installing Postfix from a pre-built package.
|
||||
# .IP -upgrade-permissions
|
||||
# Update ownership and permission of selected files/directories as
|
||||
# specified in $config_directory/postfix-files. Implies -create.
|
||||
#
|
||||
# This is required when installing Postfix from source code, while
|
||||
# Postfix was already installed on the machine.
|
||||
# .IP -upgrade-configuration
|
||||
# Edit the installed main.cf and master.cf files, in order to account
|
||||
# for missing services and to fix deprecated parameter settings.
|
||||
#
|
||||
# This is required when Postfix was already installed on the machine.
|
||||
# .IP -upgrade-source
|
||||
# Short-hand for -upgrade-permissions -upgrade-configuration.
|
||||
#
|
||||
# This is recommended when upgrading Postfix from source code.
|
||||

|
||||
# Short-hand for -set-permissions -upgrade-configuration.
|
||||
#
|
||||
# This is recommended when upgrading Postfix from a pre-built package.
|

# .IP -first-install-reminder
|
||||
# Remind the user that they still need to configure main.cf and the
|
||||
# aliases file, and that newaliases needs to be run.
|
||||
#
|
||||
# This is recommended when Postfix is installed for the first time.

# NAME

|

# SUMMARY
|
||||
# Postfix installation procedure
|
||||
# SYNOPSIS
|
||||
# sh postfix-install [-non-interactive] [name=value] ...
|
||||
# DESCRIPTION
|
||||
# The postfix-install script is to be run from the top-level
|
||||
# Postfix source directory. It implements the following operations:
|
||||
# .IP o
|
||||
# Install or upgrade Postfix from source code. This mode requires
|
||||
# super-user privileges.
|
||||
# .IP o
|
||||
# Build a package that can be distributed to other systems, in order
|
||||
# to install or upgrade Postfix elsewhere. This requires no super-user
|
||||
# privileges. To complete the installation after unpacking the
|
||||
# package, execute as super-user the post-install script in the Postfix
|
||||
# configuration directory.
|
||||
# .PP
|
||||
# The postfix-install script is controlled by installation parameters.
|
||||
# Specific parameters are described at the end of this document.
|
||||
#
|
||||
# By default, postfix-install asks the user for installation
|
||||
# parameter settings. Settings are stored in the installed
|
||||
# main.cf file. These settings are used as site-specific defaults
|
||||
# when the postfix-install script is run later.
|
||||
#
|
||||
# The names of Postfix files and directories, as well as their
|
||||
# ownerships and permissions, are stored in the postfix-files file
|
||||
# in the Postfix configuration directory. This information is used
|
||||
# by the post-install script (also in the configuration directory)
|
||||
# for creating missing queue directories when Postfix is started,
|
||||
# and for setting correct ownership and permissions when Postfix
|
||||
# is installed from a pre-built package or from source code.
|
||||
#
|
||||
# Arguments
|
||||
# .IP -non-interactive
|
||||
# Do not ask the user for parameter settings. This is useful for
|
||||
# upgrading an existing Postfix installation from source code,
|
||||
# or for preparing a pre-built package for distribution to other
|
||||
# systems. Installation parameters must be specified via one of
|
||||
# the non-interactive methods described below.
|
||||
# INSTALLATION PARAMETER INPUT METHODS
|
||||
# .ad
|
||||
# .fi
|
||||
# Parameter settings can be specified through a variety of
|
||||
# mechanisms. In order of decreasing precedence these are:
|
||||
# .IP "interactive mode"
|
||||
# By default, postfix-install will ask the user for
|
||||
# installation parameter settings. These settings have the highest
|
||||
# precedence.
|
||||
# .IP "command line"
|
||||
# Parameter settings can be given as name=value arguments on
|
||||
# the postfix-install command line.
|
||||
# .IP "process environment"
|
||||
# Parameter settings can be given as name=value environment
|
||||
# variables. Environment parameters can also be specified on the
|
||||
# make(1) command line as "make install name=value ...".
|
||||
# .IP "installed configuration files"
|
||||
# If a parameter is not specified via the command line or via the
|
||||
# process environment, postfix-install will attempt to extract its
|
||||
# value from an already installed Postfix main.cf configuration file.
|
||||
# .IP "built-in defaults"
|
||||
# These settings have the lowest precedence.
|
||||
# INSTALLATION PARAMETER DESCRIPTION
|
||||
# .ad
|
||||
# .fi
|
||||
# The description of installation parameters and their built-in
|
||||
# default settings is as follows:
|
||||
# .IP install_root
|
||||
# Prefix that is prepended to the pathnames of installed files.
|
||||
# This is useful for creating a pre-built package for distribution to
|
||||
# other systems. The built-in default is "/", the local root directory.
|
||||
# .IP tempdir
|
||||
# Directory for scratch files while installing Postfix.
|
||||
# You must must have write permission in this directory.
|
||||
# The built-in default directory name is the current directory.
|
||||
# .IP config_directory
|
||||
# Destination directory for Postfix configuration files. The
|
||||
# built-in default directory name is /etc/postfix.
|
||||
# .IP daemon_directory
|
||||
# Destination directory for Postfix daemon programs. This directory
|
||||
# should not be in the command search path of any users. The built-in
|
||||
# default directory name is /usr/libexec/postfix.
|
||||
# .IP command_directory
|
||||
# Destination directory for Postfix administrative commands. This
|
||||
# directory should be in the command search path of adminstrative users.
|
||||
# The built-in default directory name is system dependent.
|
||||
# .IP queue_directory
|
||||
# The destination directory for Postfix queues. The built-in default
|
||||
# directory name is /var/spool/postfix.
|
||||
# .IP sendmail_path
|
||||
# The full destination pathname for the Postfix sendmail command.
|
||||
# This is the Sendmail-compatible mail posting interface.
|
||||
# The built-in default pathname is system dependent.
|
||||
# .IP newaliases_path
|
||||
# The full destination pathname for the Postfix newaliases command.
|
||||
# This is the Sendmail-compatible command to build alias databases
|
||||
# for the Postfix local delivery agent.
|
||||
# The built-in default pathname is system dependent.
|
||||
# .IP mailq_path
|
||||
# The full destination pathname for the Postfix mailq command.
|
||||
# This is the Sendmail-compatible command to list the mail queue.
|
||||
# The built-in default pathname is system dependent.
|
||||
# .IP mail_owner
|
||||
# The owner of the Postfix queue. Its numerical user ID and group ID
|
||||
# must not be used by any other accounts on the system. The built-in
|
||||
# default account name is postfix.
|
||||
# .IP setgid_group
|
||||
# The group for mail submission and for queue management commands.
|
||||
# Its numerical group ID must not be used by any other accounts on the
|
||||
# system, not even by the mail_owner account. The built-in default group
|
||||
# name is postdrop.
|
||||
# .IP manpage_path
|
