Hello all, I am trying to harden the embedded system. Is it possible and safe to mount /proc file system in a read-only mode and how to do this? I have embedded system with systemd where /proc is mounted rw. I suspect that systemd mounts it when it bebins to bootsrtap user space.
On my very simple QEMU busybox system with no systemd I was able to remount /proc read-only. But when I changed fstab to mount it as a read-only it is still mounted rw,relatime after reboot So at what s boot stage and how I can mount /proc read-only ? Perhaps it is hardcoded in busybox init or in systemd ?
