# qdb/setup.sh --- wire up the qdb systemd *user* services.
#
# Run this as the user the bot should run as. That user must be a
# member of group `venusia` (so the watcher can write quotes/, which
# is group-venusia setgid).
#
# This only handles the systemd units. The Comic Chat render path has
# separate, root-level dependencies (ruby, rmagick, /opt/spittoon) ---
# see the "Comic Chat" section of README.txt. qdb works without them;
# /comic just returns a graceful error until they are in place.
#
# The unit files in systemd/ are written for the canonical deployment
# path (/var/gopher/applets/qdb). This script rewrites that path to
# wherever the qdb directory actually lives, so it also works for an
# out-of-tree checkout.
