Kay Sievers is a German computer programmer, best known for developing the udev device manager of Linux, systemd and the Gummiboot EFI bootloader. Kay Sievers made major contributions to Linux's hardware hotplug and device management subsystems.
The target of Torvald's latest tirade was Kay Sievers, one of the key developers of systemd, a system-management daemon that isn't part of the kernel but is among the first software to launch when Linux boots.

When you power on your computer, the hardware boots, and then (according to the type of boot sector your computer uses) either the master boot record (MBR) executes or the Unified Extensible Firmware Interface (UEFI) runs. The last action of both of these is to fire up the Linux kernel. The kernel is loaded into memory, decompresses itself, and ini...
Several projects have tried to produce an alternative to the traditional System V init. One of the main problems is, with System V init, all processes are started serially, one after another. To improve the efficiency of the boot sequence, many alternative projects use parallelism to start processes concurrently and asynchronously. Here's some info...
systemd was released in 2010 and was used in Fedora in 2011. Since then, it's been adopted by many distributions. It was developed by Lennart Poettering and Kay Sievers, two software engineers at RedHat. systemdis much more than an init replacement. Rather, it's a suite of approximately 70 binaries that handle system initialization, daemons and ser...
Opponents of systemdpoint out the large, curious mix of functionality it encompasses. All of these features already existed in Linux, and, perhaps, some of them needed a refresh or a new approach. However, to bundle all of this functionality in what is supposed to be an init system is architecturally puzzling. systemd has been called a single point...
Some opponents of systemdsay distributions and people are just blindly following Red Hat's lead and adopting it. However, just like the phrase, "drinking the Kool-Aid," that's not quite right. Coined in 1978 after cult leader, Jim Jones, coerced his over 900 followers to commit suicide by drinking a grape-flavored liquid laced with cyanide, the phr...
You don't generally get to choose whether to use systemd with a particular Linux distribution. Rather, the distributions themselves choose whether they want to use it, and you can choose which Linux distro you prefer. Perhaps a Linux distribution you love switched to systemd. Like a favorite musician who changes genres, this can be jarring. People ...
I like some of what systemd does (simple and standardized control mechanisms for processes). I don't understand the rationale for some of what it does (binary logs). I also dislike some of what it does (revamping home folders---who asked for that?). Distributions like Debian are doing the smart thing and investigating alternatives to keep its optio...
Systemd, which was created by Red Hat 's Lennart Poettering and Kay Sievers, does more than start the core programs running. It also starts a journal of system activity, the network stack, a cron...
The systemd developers have refused to modify the debug option to something more sensible like "systemd.debug". Steve Rostedt posted a patch to prevent systemd from using the debug keyword and Linus went off on Kay Sievers.
Kay is working most of its time on linux hotplug related topics, hacks on udev, systemd, the device management code in the kernel, and a bunch of related projects. Display proposals... Proposals for this user
