Utility to run systemd in WSL2 with a Linux namespace

subsystemctl's Issues

Shell falls back to sh on subsystemctl shell

errors

Provided a working solution to this. Enjoy :)

A note on AppArmor and WSL

Just a quick note to let you know that I've had a patch accepted into AppArmor (and have a similar one awaiting review for snapd) to support running under WSL:

https://gitlab.com/apparmor/apparmor/-/merge_requests/812

As suggested in the comments there, there's a potential issue with AppArmor profiles leaking from distro to distro and/or from container to container because of WSL's architecture, so to avoid this problem in genie, I've arranged for it to create an AppArmor namespace before starting systemd (if AppArmor support is detected in the kernel) to prevent potential leakage.

Thought I'd let the other authors of WSL systemd hacks know in case you wish to take similar measures. In case it might be useful, my implementation of this can be found here, called from here.

is this available for CentOS/RHEL?

error in command using subsystemctl exec bash

○ → /root/.cargo/bin/subsystemctl exec bash
error: Found argument 'bash' which wasn't expected, or isn't valid in this context

USAGE:
subsystemctl exec [FLAGS] [OPTIONS] [-- ...]

For more information try --help

i am using Windows 11, the latest WSL2. the bash does not exist or invalid.

but all commands are working good in Windows 10 WSL2.

please check, thank you!

by the way, you did a great job for this code, thank you very much!

WORKING GOOD in CENTOS7/RHEL7 / Oracle Linux 7

Good news! everything working smoothly in both CENTOS7 and RHEL7. Just make sure that if you want to port those Linux Distro, make sure to pull the official images in their respective repos

I am having problem using genie as I am using incorrect LINUX DISTRO as i created it by myself. It is much easier to pull official LINUX Distro in their respective official images repositories.

THANK YOU TO THE AUTHOR! SUCH A GREAT WORK!

I am arranging my github profile, and will push/upload all the LINUX DISTRO images I am using!

Not working in ssh

Running subsystemctl exec -- echo 1 will normally prints 1, but if you run it in a ssh session, it will show this:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Sys(ENOENT)', src/bottle.rs:385:18
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Some thoughts about setuid

So subsystemctl is designed to work with root privilege, which I fully acknowledge, but recently I've been experimenting with chmod +s on the executable.

What I noticed is that, after setting the setuid on subsystemctl executable, start and stop subcommands still require you invoke sudo, but the behavior of shell and exec subcommands is more interesting - you can run them without your current user as root, you can even issue the flag to, by the way, start the systemd container without problem, and you won't be automatically escalated to root if you run setuid-ed subsustemctl as a normal user - you run a new process as exactly who you are.

Just wondering if that was the expected behavior, or whether subsystemctl is supposed to work with setuid at all.

Thank you 🙂

Cockpit + KVM

the subsystemctl cannot load KVM inside the cockpit.

probably, the author may include this in his next release?

thank you!

Cannot access DISPLAY :0

The glxlgears works just fine, but executing it inside the subsystemctl says that it couldn't open display :0
In this case i use WSL Graphic via /dev/dxg

[root@LAPTOP ~]# subsystemctl start
[root@LAPTOP ~]# DISPLAY=:0 glxgears
Error: couldn't open display :0

pkg subsystemctl is removed from aur?

return 404 for now

I was able to run the subsystemctl in Centos 8

I was able to run the subsystemctl in Centos 8, however, it is the same with genie, there are few application that are depreciated, like the firewalld.

All you need to do is to compile to the latest systemd 248.3 or later. and the subsystemctl is working in WSL2.

can't cat /proc/sys/fs/binfmt_misc/WSLInterop Too many levels of symbolic links

While in the environment cat /proc/sys/fs/binfmt_misc/WSLInterop produces this error

Too many levels of symbolic links

This breaks wslu

Supports cloning environment variables such as WSL_DISTRO_NAME

Executing echo $WSL_DISTRO_NAME in subsystemctl shell currently doesn't work, others environment variables such as $DISPLAY isn't inherited too.

I think it is good to have a way to specify a list of environment variables to clone like genie does.

Missing Windows Path

When inside the systemd environment the windows paths are missing.
These paths are there when outside the system environment.
How do I automatically append windows paths when entering the system environment?
