Distribution EOLE

* EOLE >= 2.7.2
* corriger ce cas de figure (éventuellement le rendre inaccessible en imposant certaines valeurs si ce n'est pas un cas d'utilisation volontaire)
* éviter surtout les régressions car le sujet est épineux et le nombre de combinaisons possibles important !

Sur une eolebase en 2.7.2, instance faite, passage de la variable *@activer_nginx_web@* à *@non@*.

<pre>
root@eolebase:~# CreoleGet --list | grep nginx
activer_nginx_web="non"
test_activer_genconfig_nginx="oui"
test_activer_minimal_nginx="oui"
test_activer_nginx_web="oui"
test_hide_nginx_family="oui"
</pre>


+après le reconfigure nginx plante :+
