Goals of Finit

Initially Finit aimed to be more than a processes monitor, acting as a replacement for cron/at and inetd as well. Over time, however, the true value in the project turned out to be:

A simple SysV init and systemd replacement, primarily for embedded systems, container, and dedicated server applications.

Misc TODOs

Some of these are also registered in the issue tracker on GitHub.

• Refactor the .conf parser, parse user input in a separate process

• Move process monitor to separate process (same as parser?)

• Add new (complimentary) .svc file format to slowly migrate away from the very terse one-liner format currently used

• Allow running as non-pid1 => read .conf and RCSD form cmdline

• Add finit.conf support for UPS notification (SIGPWR) to start a task using, e.g. <sys/power/{ok,fail,low}> conditions. More info in sig.c

  As of Finit v4.1 SIGPWR generates <sys/power/fail> condition and it is up to a task to check why and take appropriate action.

• Add finit.conf support for ctrl-alt-delete (SIGINT) and kbrequest, i.e. KeyboardSignal, (SIGWINCH) behavior. Using conditions to a task, e.g, <sys/key/ctrlaltdel> and <sys/key/signal> like SIGPWR handling.

  As of Finit v4.1 SIGINT generates <sys/key/ctrlaltdel>, but there is no check if the signal actually originates from the kernel. To get this verification, a new libuEv release is needed. As of June 6 -21 that functionality is not yet released.

Initctl

• Add support for timed shutdown in Finit, including cancelled shutdown:

    shutdown -h 03:35 "foobar was here"
  

• Add support for JSON output, or similar, from initctl show, e.g. initctl show --json

• Add support for -s to redirect all output to syslog, for scripting

Init

Finit in itself is not SysV Init compatible, it doesn't use /etc/rc.d and /etc/init.d scripts to boot the system. However, a plausible way to achieve compatibility would be to add a plugin to finit which reads /etc/inittab to be able to start standard Linux systems.
