Bug#1056166: systemd-homed: `passwd` fails

[Jack Pearson]

Package: systemd-homed
Version: 255~rc2-1
Severity: important

Dear Maintainer,

In a minimal Debian installation, `systemd-homed` breaks `passwd`.

Just run these commands:

```
$ sudo -sE
$ debootstrap unstable unstable-dir
$ chroot unstable-dir
$ apt install systemd-homed
$ passwd
passwd: Authentication token manipulation error
passwd: password unchanged
```

I'm certain this isn't a quirk of the chroot installation, I first found this issue on Raspbian installed on actual hardware, version bookworm.
