[Unit]
Description=Onion Monero Blockchain Explorer Health Check Timer
# Deliberately NO `Requires=xmrblocks.service`. Requires on a timer stops the
# timer when the watched unit stops - "if the thing I am watching goes down,
# stop watching it" - leaving nothing to re-arm when it returns. Fulcrum's
# timer carried it and sat active+enabled for seven months without firing.
