- new install-service.sh: creates/removes the OpenCode web UI systemd service as its own process (interactive by default, flags for automation, --uninstall, --dry-run, backs up an existing unit) - install.sh no longer embeds the service logic; run_service_setup locates the sibling script (or downloads it) and invokes it as a separate process - README documents running install-service.sh on its own

# OpenAgents Control — Architect Fork · web UI service installer
|
||
# ============================================================================
|
||
# Creates (or removes) a systemd service that runs the OpenCode web UI as a
|
||
# background process:
|
||
#
|
||
# opencode serve --hostname <host> --port <port>
|
||
#
|
||
# Run it on its own, or let install.sh call it after OpenCode is installed.
|
||
#
|
||
# Usage:
|
||
# ./install-service.sh # interactive
|
||
# ./install-service.sh --port 4096 # interactive, prefilled port
|
||
# ./install-service.sh --host 0.0.0.0 --port 8080
|
||
# ./install-service.sh --yes # non-interactive defaults
|
||
# ./install-service.sh --uninstall # stop and remove the service
|
||
# ./install-service.sh --dry-run # show the unit, change nothing
|
||
#
|
||
# Environment:
|
||
# OPENCODE_SERVICE_NAME unit name (default: opencode.service)
|
||
# OAC_FORCE_SYSTEMD 1/0 to force systemd detection (containers/CI)
