			I use this technique to also have Oracle Java 8 and Apache Karaf running cleanly in run-from-ram mode without overloading the memory with storage.
			The embedded box has a read-only memory chip and system is clean and brand new at each reboot.

			To update, we remount media rw, rsync then remount ro again.

			== permanent pip install in run-from-ram with overlayFS ==

			For an embedded system, I wanted to have a few python tools installed from pip to be present at boot time without needing network to rebuild.

			<pre>
			mv /usr /usr.dist
			mkdir /usr
			mount -t overlay overlay -o lowerdir=/usr.dist,upperdir=/usr,workdir=/tmp/usr /usr
			pip install --upgrade pip
			pip install semantic_version
			pip install incremental
			pip install pymodbus
			umount /usr
			mount -o remount,rw /media/sda1
			mv /usr /media/sda1/usr.post
			mount -o remount,ro /media/sda1
			mv /usr.dist /usr
			mkdir -p /tmp/usr
			mount -t overlay overlay -o lowerdir=/media/sda1/usr.post,upperdir=/usr,workdir=/tmp/usr /usr
			</pre>
