systemd keeps running after exiting the wsl distro.

[akuropka]

Windows version (build number): 10.0.22572.100

Linux distribution: Arch Linux using wsldl.

Genie version: genie 2.0 (as per genie --version) genie 42e1d851b333a8292c4f84aba8e87eda3891f305 (actually built version)

Describe the bug With genie initialized and running as shell (genie -s) after exiting the session with exit the shell window keeps open and does not close automatically.

Confirm that you are running inside the bottle: inside

Command used during starting the shell session (e.g. .bash_profile):

# Start genie
if [[ ! -v INSIDE_GENIE ]]; then
  exec /usr/bin/genie -s
fi

To Reproduce Steps to reproduce the behavior:

1. Add above code to .bash_profile.
2. For safety's sake shut down wsl (wsl --shutdown).
3. Open a new shell.
4. exit the shell.

Expected behavior The shell window closes.

I confirm that I have read the ENTIRE supplied readme file and checked for relevant information on the repository wiki before raising this issue, and that if the solution to this issue is found in either location, it will be closed without further comment:

• [X] Yes.

Haven't had any luck reproing this so far, alas.

A couple of questions, though --

• If you start a shell in an existing command prompt window using genie -s, does it return to the command prompt on exit?
• Does this happen on second or subsequent (simultaneous) shell windows, or only the first one?

@cerebrate, thank you for your reply. Please see the screencast, maybe you have an idea... it's only after running genie.

Huh. That is very strange.

My best speculation here is that there has to be some leftover process in the session keeping the pty alive and so holding the window open. So I've got to ask you for three more things:

• the output of ps aux before running genie -s
• the output of systemctl status inside the bottle
• the output of ps aux after exiting the bottle

Hopefully that'll give us a clue as to what it might be.

ps aux before entering the bottle:

If I kill systemd and exit the shell afterwards the window closes. For reference: journal.txt

Using genie --shutdown after exiting the bottle closes all processes but brings up the following error:

I'm closing this as it seems the issue cannot be resolved. In addition I moved to a different solution.
