Thanks goes to Stefan Schlesinger, who debugged the issue and noticed the apache2->php porting error where $rcd_action was tested, but never set, thus effectively disabling dpkg-trigger.

# VARIABLES
|

|

# global environment variables used by php-maintscript-helper:
|
|
# * PHP_MAINTSCRIPT_DEBUG:
|
|
# set this to any non-zero value to get debug output
|
|
# * PHP_MAINTSCRIPT_HELPER_QUIET:
|
|
# set this to any non-zero value to omit any output
|
|
# * EXPORT_PHP_MAINTSCRIPT_HELPER:
|
|
# will be defined by php-maintscript-helper
|
|
# to avoid inclusion loops. Do not set this
|
|
# variable manually

# maintscript-helper. It contains arguments which

|
# information. These variables are an

# print out a warning to both, the syslog and a local standard output.
|
|
# This function should generally be used to display messages related to
|
|
# the web server in maintainer scripts.
|
|
# Parameters:
|
|
# priority
|
|
# The message priority. Recognized values are the same as defined
|
|
# by syslog(3), thus: one among debug, info, notice, warning,
|
|

|
|
# If no known priority is recognized, the priority is set to
|
|
# "warning".
|
|
# message
|
|
# The message as a string. It is printed out verbatim.
|
|
# Behavior:
|
|
# No message is displayed if PHP_MAINTSCRIPT_HELPER_QUIET is defined
|
|
# Returns:
|
|
# this function always returns 0
|
|
# Since: 5.5.0+dfsg-7

# Function php_invoke
|
|
# invokes an PHP configuration helper to enable or disable a
|
|
# particular piece of configuration, a site or a module. It carefully
|
|
# checks whether the supplied configuration snippet exists and reloads the
|
|
# web server if the site administrator desires that by call dpkg trigger
|
|
# /etc/php/VERSION/SAPI/conf.d which is defined for apache2, apache2filter and fpm.
|
|
#
|
|
# Parameters:
|
|
# command - The command to invoke. Recognized commands are "enconf",
|
|
# "enmod", "ensite", "disconf", "dismod", "dissite"
|
|
#
|
|
# sapi - Either the specific SAPI (apache2, apache2filter, fpm,

|
# cgi, cli, embed, phpdbg) or ALL
|
|
#
|
|
# arguments
|
|
# - A single argument (e.g. a module) which shall be
|
|
# enabled or disabled respectively.
|

#
|
|
# Returns
|
|
# 0 if the changes could be activated

# 1 otherwise
