Note that: df /dev/watchdog as root still causes the system to reboot on Linux. Not a POSIX conformance issue as the behaviour is unspecified for device files without a mounted file system on, but still not ideal. The point is that opening files has or can have side effects and df is not *meant* to open files. I would think that automounting directories assuming we do want it to happen should be enough unless someone can come up with a realistic use case where non-directory files are being automounted (and assuming that's possible). -- Stephane
