From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The main reason is that Dbus is not available during early stages of boot. There are many others.

Varlink seems to be better or the same compared to dbus in all except two things:

json doesn't handle 64bit integers, it handles 52bit (or 54bit?) (size of mantissa for floats)
you cannot (yet) list all things connected to the bus
