        Note that this schema does not check whether the UID exists (has
        record in the user database e.g. "/etc/passwd"). To do that, use the
        "unix::uid::exists" schema.

    *   unix::uid::exists

        User identifier (UID) that has to exist (has associated username) on
        the system.

        Existing means having a user name associated with this UID, i.e.
        "getpwuid" returns a record.

        Support coercion from an existing user name.

    *   unix::username

        Unix account name.

        The checking follows POSIX rules: does not begin with a hyphen and
        only contains [A-Za-z0-9._-].
