| ===== 嵌入系统 ===== |
| ==== 硬盘IO备忘==== |
| * ''/var/lib/ntp/ntp.drift'' 文件, nptd服务,记录本地时钟频率差异 每小时修改一次, 可在''/etc/ntp.conf''更改; |
| * ''/etc/adjtime'' 文件, hwclock操作会修改此文件; |
| * ''/var/logrotate/status'' logrotate服务所用, 每天修改一次; |
| * ''/etc/fake-hwclock.data'' fake-hwclock所用, 每小时及关机时修改, 用于启动时读取, 所以不能改至tmpfs; |
| * ''/var/lib/monit/state'' monit服务所用, 以monit监测的频率被修改, 可在''/etc/monit/monitrc''配置修改位置至tmpfs; |

| ===== 串口线插法 ===== |
