    #
# Do not edit this file.
#
# This file controls the postfix-install script for installation of
# Postfix programs, configuration files and documentation, as well
# as the post-install script for setting permissions and for updating
# Postfix configuration files. See the respective manual pages within
# the script files.
#
# Do not list $command_directory or $shlib_directory in this file,
# or it will be blown away by a future Postfix uninstallation
# procedure. You would not want to lose all files in /usr/sbin or
# /usr/local/lib.
#
# Each record in this file describes one file or directory.
# Fields are separated by ":". Specify a null field as "-".
# Missing fields or separators at the end are OK.
#
# File format:
#	name:type:owner:group:permission:flags
#	No group means don't change group ownership.
#
# File types:
#	d=directory
#	f=regular file
#	h=hard link (*)
#	l=symbolic link (*)
#
# (*) With hard links and symbolic links, the owner field becomes the
#     source pathname, while the group and permissions are ignored.
#
# File flags:
#	No flag means the flag is not active.
#	p=preserve existing file, do not replace (postfix-install).
#	u=update owner/group/mode (post-install upgrade-permissions).
#	c=create missing directory (post-install create-missing).
#	r=apply owner/group recursively (post-install set/upgrade-permissions).
#	o=obsolete, no longer part of Postfix
#	1=optional for non-default instance (config_dir != built-in default).
#
# Note: the "u" flag is for upgrading the permissions of existing files
# or directories after changes in Postfix architecture. For robustness
# it is a good idea to "u" all the files that have special ownership or
# permissions, so that running "make install" fixes any glitches.
#
# Note: order matters. Update shared libraries and database plugins
# before daemon/command-line programs.
