mount --make-rshared / 

xref: https://github.com/conda-forge/podman-feedstock/issues/25

Use wsl.exe "trick" to run this at the start. (Should use boot settings on Win11)

$ cat /etc/profile.d/02-shared-root.sh
wsl.exe -u root -e mount --make-rshared /

Avoids below error:

WARN[0000] "/" is not a shared mount, this could cause issues or missing mounts with rootless containers

/tmp is a directory on WSL and without the systemd config the podman temp files don't get cleaned up resulting in unknown FS magic errors.

Ensure /tmp is cleaned up by mounting a tmpfs in /etc/fstab:

$ cat /etc/fstab
LABEL=cloudimg-rootfs   /        ext4   discard,errors=remount-ro         0 1
tmpfs                   /tmp     tmpfs  rw,nosuid,nodev,noatime,mode=1777 0 0
