dev/<X> only fires when a device gets a /dev node, which leaves a lot of
embedded-relevant hardware uncoverable: DSA switch cores, IIO sensors,
LEDs, backlight, PHYs, regulators -- all live purely under sysfs.
Two new condition namespaces:
class/<subsystem>/<sysname> asserted on every sysfs class device add
(e.g. <class/leds/blue>)
driver/<name> asserted while the driver is bound to at
least one device (e.g. <driver/mt7530>)
A driver can bind to several devices, so driver/ conditions are
refcounted: asserted on first bind, cleared when the last device is
unbound.
dev_cond() is generalized into a static cond_emit(prefix, rel, set) so
class_cond() and driver_cond() share the same mkpath + symlink/erase
code. The name avoids colliding with src/cond.h's public cond_path()
helper (unrelated function that returns a condition's filesystem path).

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.
