ExecStart=/home/lkraven/.local/bin/headscale-ddns.sh

# /home/lkraven/.config/systemd/user/headscale-ddns.service.d/10-onfailure-althing.conf
# Installed as <unit>.service.d/10-onfailure-althing.conf on every fleet user
# unit. A drop-in rather than an edit to the unit file so it is visible in
# `systemctl --user cat`, reversible by deleting one file, and survives the
# unit being reinstalled by its own deploy.
#
# %n is the failing unit's full name; the template receives it as %I.
