[Bug]: systemd not working

[colemar]

Describe the bug

Installed Distrod (via install.sh) in an existing WSL2 distro Ubuntu 22.04.1 LTS (Jammy Jellyfish). There is a pre-existing Debian distro with Distrod (via install.sh) that seems to work OK.

As soon as the Ubuntu distro is started vmmem process gets about 15% CPU as stated by Windows Task Manager. Inside the distro:

• top shows systemd at 100% CPU.
• systemctl hangs for a while then spits: Failed to list units: Transport endpoint is not connected
• sudo grep 'Distrod:' /dev/kmsg just hangs forever As soon as the Ubuntu distro is stopped (wls -t Ubuntu) vmmem process goes down to 0% CPU. I see nothing particularly wrong in the Distrod trace log.

I installed another Ubuntu 22.04 distro via distrod_wsl_launcher.exe and it works as expected.

Steps to reproduce

See above.

Expected behavior

systemd works

Windows version

Windows 10 21H2 19044.2006

Linux kernel version

5.10.102.1-microsoft-standard-WSL2

Distro

Ubuntu 22.04

How did you install that distro?

Enabled distrod in an existing WSL2 distro

What version of the systemd package?

It seems the last one (250.*) is broken: https://github.com/microsoft/WSL/issues/8879

[colemar]

@psmolkin systemd 249.11-0ubuntu3.6 And it is the same version that is working in the other ubuntu distro which was installed via distrod_wsl_launcher.exe.
