# This script creates an unprivileged user to run the FoundryVTT daemon and
# adds a systemd unit file to run the daemon on startup.  You will need to have
# the foundry zip for linux in the directory you run this script from and you
# will need to edit the variables to suit your preferences. 
# For setting up storage on a raspberry pi, instead of relying on the auto-
# mount feature, you'll want to set up a boot-time mount
# https://www.raspberrypi.org/documentation/configuration/external-storage.md
# has more info on that.
# I reccomend that you set up a storage device as a Linux native filesystem,
# such as ext4 so that permissions are managed properly.
