Overlayfs/ readonly rootfs | system on USB (1 reply)

Dear all,

has anybody successfully installed a Debian system (>jessie) with read-only rootfilesystem (on USB stick)? I read guides on how to do that on non-ARM platforms. What are the steps in detail?

- new kernel necessary? or build at least a kernel-module?
- install overlayroot package and configure it with "tmpfs" like:

apt-get install overlayroot
echo 'overlayroot="tmpfs"' >> /etc/overlayroot.conf
reboot

- anything to do with uboot or boot commands?

Thanks!
best
