# (Re)write /usr/local/bin/klonkt-update so it matches how this server runs.
#
# Why this exists: the updater is generated once at install time. A server
# that later migrated to the split layout (klonkt@<slug> units) kept its old
# updater, which still restarts the retired klonkt.service. Result: the code
# on disk updates, the restart quietly fails, and the old process keeps
# serving — half old routes, half new templates, which is how you get a 500
# on one page and nothing in the logs that says why.
#
# Idempotent; safe to run any time:
#
#     sudo bash /opt/klonkt/scripts/klonkt-refresh-updater.sh
