The initial implementation was done using a naive translator of the
legacy one-liner format key by key, so it inherited encodings that the
block format exists to remove: a timeout packed into a script path, a
small comma-and-colon language inside the log string, sigils standing in
for booleans, and a log key (services) carrying three (!) types.
Settled naming against systemd, OpenRC, FreeBSD rc.subr, s6 and SMF.
Match systemd's semantics, not its naming.
pid -> pidfile, plus pidfile-create for the rare case
where Finit writes the file rather than the daemon
environment -> envfile, since it names a file to source, and the
top-level environment {} block sets variables
pre/post/... -> exec-start-pre, exec-start-ready, exec-stop,
exec-stop-post, exec-reload, exec-cleanup, each
with its own -timeout instead of "SEC,script"
halt, kill -> stop-signal, stop-timeout
restart -> restart for the policy, restart-max for the count
log -> a block with file, priority and identity, where
/dev/null and /dev/console are spelled as paths
group -> group and extra-groups, no longer positional
nowarn -> a leading - on command, as on envfile
List-valued keys take plural names. Aliases are desc, cond, mod,
caps, env, halt and kill; an alias may abbreviate the canonical name
or preserve a legacy spelling, nothing else.

Finit is a fast, simple alternative to SysV init and systemd, designed for small and embedded Linux systems. It can also run on desktop and server systems, like finix.

For working examples, see the 🚀 contrib/ section or these tutorials:
- 🛠️ Buildroot embedded Linux,
- 📦 Debian GNU/Linux,
- ⛰️ Alpine Linux, and
- 🌌 Void Linux
Note
Finit can run on various Linux distributions, but the bundled install scripts are examples only. They have been tested on amd64 (x86_64) systems with standard configurations.
For embedded systems, see these Buildroot-based examples: myLinux, Infix, or br2-finit-demo.
