Hello,

I'm using buildroot 2022.02.1 under x86 embedded SBC.
The root file system is located on the on-board disk.
The boot argument contains 'ro' (checked with /proc/cmdline after login)
but the disk is not read-only.

When I used the same boot args with busybox, it worked fine.
Of course with busybox I had to tailor all other mandatory files and
directories.

I need read-only rootfs to defend this embedded system in case of
power-down / cold reset.

Beyond the default configuration, the rootfs also contains ntp client,
httpd, pci tools.

Thank you,
Zvika
