journal tree, but used the host machine ID when matching namespace
directories.
Reproducer:
root="$(mktemp -d)"
mid=11111111111111111111111111111111
mkdir -p "$root/etc" "$root/var/log/journal/$mid.testns"
printf '%s\n' "$mid" >"$root/etc/machine-id"
journalctl --root="$root" --list-namespaces --quiet
