I’m a long time kernel developer and fixer of difficult problems. I spent a lot of time as a maintainer of Btrfs and lead developer. I’ve worked in a variety of kernel areas to fix problems, and lately have been focusing my time on building systing, a tool to help me debug difficult issues.

Kai

I've been using NixOS for several years now, and through it, I discovered the flexibility and power that systemd offers. However, while working with systemd units, I often found myself stuck in a slow and tedious feedback loop; constantly switching between commands just to start, check, debug, and edit units. That frustration led me to build isd: a terminal user interface to streamline systemd workflow for newcomers and experienced users.

My goal with isd is to make interacting with systemd faster, more intuitive, and enjoyable.
