Two scripts, one is the system service so that the ram disk is re-instated upon reboot, ram volatility is obviously the situation with ram disks and the ram disk script.

Setup RAM disk service on Linux

# Filename: setup-ramdisk.service
# /etc/systemd/system/setup-ramdisk.service
# sudo cp /home/x/ram_disk/setup-ramdisk.service /etc/systemd/system/setup-ramdisk.service
# sudo systemctl daemon-reload
# sudo systemctl enable setup-ramdisk
# sudo systemctl start setup-ramdisk
# After reboot check with df -h | grep ramdisk
# sudo systemctl status setup-ramdisk

The second script involves keeping a copy of linux as chrooted jail for a user. Alpine Linux is sufficiently small that its works for this purpose. The second program is named schroot, apt-get install schroot. Putting the ram disk in a chroot jail insures we do not use the disk at all, a lib or two could sneak under the radar causing a bottleneck.
