Intended use of non-root-user manipulation of /etc/passwd

[jennydaman]

Hello, I am confused about this code's intent.

autossh/rootfs/entrypoint.sh

Lines 27 to 32 in 816f453

	# Add entry to /etc/passwd if we are running non-root
	if [[ $(id -u) != "0" ]]; then
	USER="autossh:x:$(id -u):$(id -g):autossh:/tmp:/bin/sh"
	echo "[INFO ] Creating non-root-user = $USER"
	echo "$USER" >> /etc/passwd
	fi

If the user is not root, then they don't (unlikely) have write permission to /etc/passwd. So this block of code fails most of the time.

To run jnovack/autossh as a non-root user, I used a workaround where I pre-create /etc/passwd and mount it as a read-only volume.

That's a great point. What do you suggest for changes?
