Reference sections kept pointing at the line-based format they no longer
document. `sysv` and `task` sent the reader to Services for "<COND>",
the cgroups chapter opened by listing three legacy directives and then
explained further down that only two of them exist here, and the logging
chapter still gave "log:prio:facility.level,tag:ident" as the full
syntax.
Some claims were wrong independent of the format:
- a sysv is a supervised daemon, grouped with service in
SVC_TYPE_DAEMON, not a variation on task
- restart-max has no upper bound of 255, or any other
- the built-in rescue fallback runs in 12345789, not 12345
- conditional loading quotes system/10-hotplug.conf, not
system/hotplug.conf
- the key spells conflicts, not conflict
- the built-in getty no longer wants TERM last, it is a key
`if` takes either a service name or, in angle brackets, a condition,
decided in svc_ifthen(). Only the examples showed this, so it is now
said.
Terminology follows the split index.md already draws: a block is the new
format, a stanza the line-based one.
src/rescue.conf was still line-based, missed because it sits in src/
rather than system/ or contrib/.

Templating
|
|
==========
|
|
|
|
Finit comes with rudimentary support for templating, similar to that of
|
|
systemd. Best illustrated with an example:
|
|
|
|
$ initctl show avahi-autoipd@
|
|
service avahi-autoipd:%i {
|
|
description = "ZeroConf for %i"
|
|
command = "avahi-autoipd --syslog %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 be replaced with `eth0` before the file is
|
|
parsed, so it works in the block title, in any value, and in the
|
|
command line alike. Inspect the result with `initctl show
|
|
avahi-autoipd:eth0`, and check a running instance with:
|
|
|
|
```
|
|
$ initctl status avahi-autoipd:eth0
|
|
Status : running
|
|
Identity : avahi-autoipd:eth0
|
|
Description : ZeroConf for eth0
|
|
