Four templates use backslash line-continuation on ExecStart (decnet-bus, decnet-forwarder, decnet-listener, decnet-updater). My earlier sed inserted StandardOutput= and StandardError= right after the first ExecStart= line, which split the command and systemd fed those two lines back to the binary as extra positional arguments — the bus in particular crashed with: Got unexpected extra argument (StandardOutput=append:/var/log/decnet/decnet.bus.log) Walk the ExecStart block (follow \-continuation lines) and insert the two Standard* directives AFTER the last continuation line. The nine single-line ExecStart templates are unaffected in shape but re-written through the same path to keep the whole set uniform.
