I've built and installed the oz package succesfully on Debian 9.3 (no hardened kernel), I've tested it and works fine with offline apps (e.g. evince), while it's giving me hard time with (the clearnet and) Chromium.
I've kept chromium.json intact and I've to say that last time I've tried it on SubgraphOS there were no problems, maybe it can be related to the new Chromium version.
