1	#!/bin/bash
2	# Sets up EdenFS on the hub server.
3	# EdenFS runs on the HOST (not in Docker) because it needs FUSE access.
4	#
5	# Prerequisites:
6	# - grove/edenfs:latest Docker image must be built
7	# - Mononoke SLAPI must be running (grove.host:8443)
8	# - TLS client certs at /data/grove/tls/
9	#
10	# What this does:
11	# 1. Extracts edenfs + edenfs_privhelper binaries from Docker image
12	# 2. Creates EdenFS config pointing at Mononoke SLAPI
13	# 3. Creates a backing repo (metadata-only sl clone)
14	# 4. Installs a systemd service for the edenfs daemon
15	# 5. Creates an EdenFS mount at /mnt/sapling
16	#
17	# Usage: sudo bash setup-edenfs.sh
