Maintanence Note: You may want to usenullpo-head/wsl-distrod which provides better compatibility with systemd and easier installation, and well maintained.
Run systemd under Linux namespace in WSL2. Heavily inspired byarkane-systems/genie, but written in Rust.
Slightly followinggenie's behavior, but noted below...
- Interface
- Command line interface is not compatible.
- Behavior
- Hostname altertion is optional with
--hostname,--hostname-suffix/etc/hostsare not updated. Users are encouraged to usenss-myhostname.
- Uses
machinectl shellto launch a user shell; this allows running systemd user session
- Hostname altertion is optional with
- Internal
- Removed dependency to
unshare,daemonize,nsentercommand line tools - systemd-wide environment variables are set via
systemd.confdrop-in, usingDefaultEnvironment= - systemd PID from root namespace is stored at
/run/subsystemctl/systemd.pid
- Removed dependency to

(PKGBUILD originally submitted to AUR (https://aur.archlinux.org/packages/subsystemctl) was deleted asthey unwelcomes WSL-exclusive packages.)
