Can't install SSH keys for root user

[icedream]

Everything except for a few paths such as the pre-overlayed /etc and /var are read-only, including the root user home directory (/root).

• Install overlay for root user or at least change its $HOME to somewhere under /media/az01-internal/

Currently changing the home directory for the user in /etc/passwd to something like /mnt/az01-internal/root and creating the directory works around it. Technically not safe for future firmware updates though.

I have used a bit different approach to get it working,

had no issues, just works!
