is it possible to mount the rootfs read-only with a system that is created with buildroot?
This was at least possible with a former system based on BSP 2.0.
I'm trying this (immediatelly after bootup is finished):
mount -r -o remount /
The result is:
mount: Mounting /dev/root on / failed: Device or resource busy
Is it possible, in general, to boot the rootfs read-only with a buildroot system?
