A sample systemd unit file that can be used to run ircd via jsexec

I'm using this on cvs.synchro.net along with an override.conf file in
/etc/systemd/system/ircd.service.d/

[Service]
ExecStart=
ExecStart=/sbbs/exec/jsexec -A -L7 -hcvs.synchro.net ircd.js -a cvs.synchro.net
LimitCORE=infinity

install/systemd/ircd.service

+# Synchronet IRCd startup file
+# Only for use when you want the ircd.js to run via jsexec, separate from sbbs
+# You should have the ircd service *disabled* in your sbbs/ctrl/services.ini
