(Off-list, please keep private) If you are accepting user-generated input, I 
strongly recommend not to rely on -dsafe. Although I haven’t had the time to 
address this so far (and I suspect it is not possible), I have found several 
breaches in it that make exploiting it easy. One of them was even discussed 
publicly some time ago on the lilypond-devel list. Instead, use --jail or some 
kind of contenerization.
