Rootless podman service fails to start

[DCsunset]

Describe the bug

Systemd user service podman.service for rootless podman will show the following errors when started:
Error: command required for rootless mode with multiple IDs: exec: "newuidmap": executable file not found in $PATH

When I add shadow package to override the path of the systemd user service, a new error would occur:

newuidmap: write to uid_map failed: Operation not permitte
should have setuid or have filecaps setuid: exit status 1

Steps To Reproduce

Steps to reproduce the behavior:

1. Set virtualisation.podman.enable = true in /etc/nixos/configuration
2. Start podman.service after login.

Expected behavior

The user service podman.service should be started without error.

Hi, Thanks for your reply. I've updated nixpkgs and updated the metadata in this issue. However, podman.service still fails to start and the error message is the same

the error message is the same

Which error message?

When I add shadow package to override the path of the systemd user service,

If you're still doing this remove it, the podman module handles it.

After removing the shadow package, it now works without problem. Thank you very much!
