定制生成的清单

使用 svcbundle 命令生成的服务清单可能无需进行任何修改即可满足您的需要。以下示例显示了对服务清单的修改。

如果修改了服务清单，请使用 svccfg validate 命令确保清单仍然有效。

示例 13-4  定制服务清单：延长允许脚本运行的时间

在生成的服务清单的以下副本中，已增大了 start 方法的缺省 exec_method 超时值（60 秒）。请确保 start 方法有足够的时间运行首次引导脚本。

            you may wish to provide a method to reread the SMF repository
            and act on any configuration changes.

示例 13-5  定制服务清单：确保脚本在安装非全局区域之后运行

在以下服务清单摘录中，svc:/milestone/multi-user 上的依赖性已更改为 svc:/system/zones-install 上的依赖性，以确保首次引导脚本在安装所有非全局区域之后运行。

<!--
    The following dependency keeps us from starting until all
    non-global zones are installed.
-->
<dependency restart_on="none" type="service"
    name="ngz_dependency" grouping="require_all">
    <service_fmri value="svc:/system/zones-install"/>
</dependency>
