This is a Buildroot external that provides the Finit init system. See the blog post, below, for more information on the advantages of using Finit in embedded Linux systems.
For an example of how to use Finit in your project, see br2-finit-demo, you can even try out the latest build in Qemu yourself:

The skeleton installs all known services as available/, even though you
may not have selected any of them in make menuconfig. When a service is
selected it will (by default) be enabled/. However, since some systems have
management software that enable services based on system configuration, this
behavior can be changed using menuconfig:
Symbol: BR2_PACKAGE_SKELETON_INIT_FINIT_ENABLE [=y]
Type : bool
Prompt: Enable selected services by default
Location:
-> External options
-> Fast Init
-> Target packages
-> System tools
-> finit init skeleton
Please note, some services, e.g., dsnmasq, chrony, etc. require additional
configuration files. These can be provided with a BR2_ROOTFS_OVERLAY.
