Templating

Finit comes with rudimentary support for templating, similar to that of systemd. Best illustrated with an example:

$ initctl show avahi-autoipd@
service :%i avahi-autoipd --syslog %i -- ZeroConf for %i

To enable ZeroConf for, e.g., eth0, use

$ initctl enable avahi-autoipd@eth0.conf

The enabled symlink will be set up to avahi-autoipd@.conf and every instance of %i will in the instantiated directive be replaced with eth0. Inspect the resulting instantiated template with initctl show avahi-autoipd:eth0 and check the status of a running instance with:

$ initctl status avahi-autoipd:eth0
     Status : running
   Identity : avahi-autoipd:eth0
Description : ZeroConf for eth0
     Origin : /etc/finit.d/enabled/avahi-autoipd@eth0.conf
