# WROLPi release poller (oneshot, driven by wrolpi-release.timer).
#
# Checks GitHub for a newly-published release and builds + publishes it.
# This is OUTBOUND polling only -- GitHub never connects to this machine.
#
# Install (as root):
#   cp release/wrolpi-release.service release/wrolpi-release.timer /etc/systemd/system/
#   # edit paths/user below to match this host, then:
#   systemctl daemon-reload
#   systemctl enable --now wrolpi-release.timer
#
# The builds need root (chroot), so this runs as root.  s3cmd therefore reads
# /root/.s3cfg by default -- either place the Spaces credentials there or point
# S3CFG at another location below.
