This resolves an issue that occurs (mostly) when OpenWrt is booted directly from a mass storage device (e.g x86 or ARM EFI, SATA, NVMe etc.) and results in the system becoming unusable (everything but / is unmounted).
When "block autofs start" is called (e.g by LuCI when editing system mounts), it was generating a "remove" hotplug event for the root device, causing the system to try to unmount the root partition. To resolve this issue, ensure no hotplug events are generated for the "/", just as we don't for the extroot usecases.
