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.
- Systing: tracing for the lazy

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.
