The matrix drops privileges from root to daemon after it starts up. This is causing all kinds of issues where the daemon user seemingly doesn't have read permissions on a lot of different files. It's also recommended to use absolute paths (fixed in #519 already)
Main symptom this works around is not being able to find a cert from certifi in the new virtual environment, causing the scoreboard to crash on startup
I tried tweaking permissions on venv/* but did not seem to have an effect. It's likely still a pathing issue that would be difficult to work around.
