>Yes, except that none of the tools in question have any support for doing that and so mounting the filesystem read-only rather than read/write would break them. All 4 of the tools (that can even be wrapped in a shell script until they are, as systemd devs say, "fixed"). >And congratulations, now you've still got a window where something can still break everything while the filesystem is mounted read/write (what happens if the tool crashes during that phase?). Better to open a window in the morning then to tear down the whole wall forever.
