Devilbox .ini file is not recognized

Question

I'd like to enable debugging on my devilbox server, on Fedora 39.

I have written a devilbox-php.ini configuration in cfg/php-ini-8.2:

; ############################################################
; # Devilbox php.ini: Xdebug example
; ############################################################
;
; Information
; -----------
; * Do not edit this file (it belongs to git)
; * This file show a possible Xdebug example configuration
; * If this file is enabled, it will overwrite the current Xdebug settings
;
; How to enable?
; --------------
; * Copy this file to another file with ".ini" extension
; * Only files with ".ini" extensions will be applied by PHP



;
; PHP.ini configuration
;
[PHP]

; Xdebug
; https://3.xdebug.org/docs/upgrade_guide
; Use these settings to enable Xdebug for PHP
; Make sure to read up on Xdebug some settings might significantly slow down requests.
; The following is just an example configuration and should be adjusted
xdebug.default_enable=1
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_host=host.docker.internal
xdebug.remote_port=9000
xdebug.remote_autostart=1
xdebug.idekey=PHPSTORM
xdebug.remote_log=/var/log/php/xdebug.log
xdebug.remote_connect_back=0

; vim: set ft=dosini:

but when I run docker exec devilbox-php-1 php --ini I don't see my config file in the list, only the default ones:

Also, the debugger isn't working obviously. According to the documentation: The file must end by .ini in order to be sourced by the PHP-FPM server., which is obviously satisfied. Running docker exec devilbox-php-1 ls -la /etc/php-custom.d/, I can see the file in question:

└─▪ docker exec devilbox-php-1 ls -la /etc/php-custom.d/
