hmmm, but since like you said above the After dependency was not taken 
into account as there is no alias, registering failure should not 
prevent rsyslog to be activated (at boot, it end up being dead) ?

I didn't though indeed about these timing diffrences but, again, without 
the After= having any effect, it should not matter, should it ?


So I'm still convinces I'm missing something obvious...

Thanks for your help
