# Run as root from a directory holding exactly the files named in SHA256SUMS.
# Effects: /opt/railiance-platform/mas-backup/, four systemd units,
# /etc/mas-backup/age-recipient (public key). Timers are enabled only after
# the first backup and freshness check pass. Does not scale, roll or restart
# the MAS facility and never deletes retained objects.
