pfSense

As an example, the freeradius package defines the following in its xml:

    <custom_php_install_command>
        freeradius_install_command();
    </custom_php_install_command>

This function freeradius_install_command() calls freeradius_dictionary_resync() which overwrites the file /usr/local/etc/raddb/dictionary. With freeradius3 version 0.15.14, the function freeradius_dictionary_resync() was updated to reference the new location of the dictionary.pfsense file: from /usr/share/doc/radius/dictionary.pfsense to /usr/local/share/pfSense/radius/dictionary.pfsense.

After a system upgrade, the package is updated as expected:

pfSense-pkg-freeradius3: 0.15.13 -> 0.15.14 [pfSense]

However, radiusd fails to start because the old location is still referenced:

# Local dictionary, does not need to include the master dictionary
ATTRIBUTE         MOTP-Init-Secret         900     string
ATTRIBUTE         MOTP-PIN             901     string
ATTRIBUTE         MOTP-Offset             902     string

$INCLUDE /usr/share/doc/radius/dictionary.pfsense
$INCLUDE /usr/local/pkg/dictionary.mpd

Reinstalling the package from the System > Package Manager page regenerates the file and the freeradius3 service is able to start. This indicates that the package post-install hook is not triggered with ZFS upgrades.
