The Heated KDBUS Debate For The Linux Kernel Has Fizzled Out

KDBUS, the new in-kernel IPC mechanism modeled after D-Bus, wasn't accepted for Linux 4.1. Since the end of the Linux 4.1 merge window, the debate over KDBUS continued, but in the past two weeks the discussion settled down.

One of the quotes leading to the discussion settling down was an arguably comical quote by Harald Hoyer. In arguing in favor of KDBUS/D-Bus, Hoyer wrote with a very lengthy post:

dbus _is_ such an easy, flexible standard IPC mechanism. Of course, you can invent the wheel again (NIH, "we know better") and wait and see, if that works out. Until then the whole common IPC problem is unresolved and Linux distributions are just a collection of random software with no common interoperability and home grown interfaces.

One of the last posts in that kernel mailing list thread was calling those comments BS. For those living under a stone, Harald Hoyer is employed by Red Hat and is one of the systemd developers along with having worked on Gummiboot, Dracut, and udev.

There were then just a few other comments the first week of May but no further on-list KDBUS discussions this week.

Do you think KDBUS will make it into the kernel under its current design? Have systemd developers gone too far? Share your thoughts by commenting on this article in our forums.
