Known forudev, systemd, Gummiboot

Kay Sievers is a German computer programmer, best known for developing the udev device manager of Linux,[1] systemd[2] and the Gummiboot EFI bootloader.[3] Kay Sievers made major contributions to Linux's hardware hotplug and device management subsystems.[4] In 2012, together with Harald Hoyer, Sievers was the main driving force behind Fedora's merging of the /lib, /bin and /sbin file-system trees into /usr, a simplification which other distributions such as Arch Linux have since adopted.[5]

In April 2014, Linus Torvalds banned Sievers from submitting patches to the Linux kernel for failing to deal with bugs that caused systemd to negatively interact with the kernel.[6]

Kay Sievers worked for Red Hat, Inc. until 2019,[3] Sievers previously worked for Novell.[2][7]

Kay Sievers grew up in East Germany[8] and nowadays[when?] resides in Berlin, Germany.[9][failed verification]
