# install.sh — RemSound UDP relay installer for a stock Raspberry Pi (or any
|
||
|
|
# systemd Linux). Idempotent: re-running it just refreshes the files and
|
||
|
|
# restarts the service.
|
||
|
|
#
|
||
|
|
# Run with sudo from inside this folder:
|
||
|
|
# sudo ./install.sh
|
||
|
|
#
|
||
|
|
# What it does:
|
||
|
|
# 1. Sanity checks: systemd present, python3 present.
|
||
|
|
# 2. Copies remsound-relay.py to /usr/local/sbin/.
|
||
|
|
# 3. Copies remsound-relay.service to /etc/systemd/system/.
|
||
|
|
# 4. Creates an empty /var/log/remsound-relay.log if missing.
|
||
|
|
# 5. systemctl daemon-reload, enable + start the service.
|
||
|
|
# 6. Prints status and the last few log lines so you can see it's alive.
