Hi Kay; thanks for taking the time to write this down
I understand what you guys are saying; and at first sight I am on the safe side here though (as the name suggests, pl_sysinit will only mount filesystems and init network interfaces and the like)
However your answers do not shed any light on the reason why pl_sysinit does not seem to be triggered *at all* (unless again this is only an artifact of the output policy)
