This avoids possible errors if `passwd --expire root` is
set during package installation.

This flag is necesssary as

```
USER_root[expire] = "1970-01-01"
```

disables the root account and displays the message:

If the user tries to login the following message is displayed:

```
Your account has expired; please contact your system administrator.
Authentication failure
```
