Supervisord configuration for bitcoind

While migrating my website that also runs a bitcoin testnet faucet I decided to finally automate the bitcoind startup using supervisord. I had already done that in other locations but had forgotten some important settings. Bitcoind takes some time to start, and supervisord needs to know. I also had to set the HOME environment variable, I don't remember why to be honest.

[program:bitcoind]
command=/usr/local/bin/bitcoind
directory=/srv/bitcoin
environment=HOME="/srv/bitcoin",PATH="/usr/bin:/usr/sbin"
user=bitcoin
group=bitcoin
autostart=true
autorestart=true
startsecs=60
startretries=3
stopwaitsecs=600
stopsignal=TERM
