99f1a2e	1	#!/bin/bash
99f1a2e	2	# Sets up EdenFS on the hub server.
99f1a2e	3	# EdenFS runs on the HOST (not in Docker) because it needs FUSE access.
99f1a2e	4	#
99f1a2e	5	# Prerequisites:
99f1a2e	6	# - grove/edenfs:latest Docker image must be built
99f1a2e	7	# - Mononoke SLAPI must be running (grove.host:8443)
99f1a2e	8	# - TLS client certs at /data/grove/tls/
99f1a2e	9	#
99f1a2e	10	# What this does:
99f1a2e	11	# 1. Extracts edenfs + edenfs_privhelper binaries from Docker image
99f1a2e	12	# 2. Creates EdenFS config pointing at Mononoke SLAPI
99f1a2e	13	# 3. Creates a backing repo (metadata-only sl clone)
99f1a2e	14	# 4. Installs a systemd service for the edenfs daemon
99f1a2e	15	# 5. Creates an EdenFS mount at /mnt/sapling
99f1a2e	16	#
99f1a2e	17	# Usage: sudo bash setup-edenfs.sh
