I just use self discipline for permadeath and until recently for no portals. If I die, I just start over. It's worked out, because I enjoy the exploration and earlier part of the game better. (Plus you never have to do corpse runs.) I only finished yaggluth once. For the nomap and actual noportals options you may have to enable dev commands like I did. Google instructions for that (says it might corrupt saves.)
