# BindsTo= in the converter unit only propagates stop, so a restart of
# {{ wireguard_ipv6_converter.service.bindTo }} leaves the converter dead and the re-created
# interface without its IPv6 addresses. Start it again whenever
# {{ wireguard_ipv6_converter.service.bindTo }} starts. --no-block because the converter orders
# itself After={{ wireguard_ipv6_converter.service.bindTo }}.
# Upholds= additionally restarts the converter whenever it stops while
# {{ wireguard_ipv6_converter.service.bindTo }} is active, e.g. after it exhausted its start limit.
