# # 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.
