My apologies! > Much of the code hasn’t changed, and, I would suspect, is largely secure. Good to know. :) I wonder how many relevant parts have changed in 9front? There are regular kernel changes, some of which were made to handle the heavy shell-script load of running werc sites. (For a short time, the load on cat-v.org was very heavy.) > But you’re talking implementation security versus architectural security.
