adb kill-server
assuming rd2 already exists. The following lasts for boot session.
mount -t ramfs -o size=2g ramfs /tmp/rd2
To make permanet in /etc/fstab , below. Note that the uid stuff does not do what I indent. You have to change the permissions of /tmp/rd with every boot. I have not systematically solved that one yet. Also, I do not know what all the params mean. I know that the following seems to work.
ramfs /tmp/rd ramfs rw,exec,uid=bob,size=2G 0 0
