I have seen that too: not AppArmor, not SELinux, but some "security"
feature of systemd, mounting (bind-mount?) things like /etc read only:
in that case, the error message /is/ actually correct.

No systemd here, so I can't check. No idea either whether those mounts
are "just" for services like the web server or more widespread.
