+# Service hardening options
+# These were added in PR #6953 to solve issue #6952, but some combination of
+# them causes "restart.sh" functionality to break with the following error:
+#   sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the
+#   'nosuid' option set or an NFS file system without root privileges?
+# See issue #7503 for details on the troubleshooting that went into this.
+# Since these were added for NixOS specifically and are above and beyond
+# what 99% of systemd units do, they have been moved here as optional
+# additional flags to set for maximum system security and can be enabled at
+# the administrator's or package maintainer's discretion.
+# Uncomment these only if you know what you're doing, and doing so may cause
+# bugs with in-server Restart and potentially other functionality as well.
