>Description:
We have many servers located in datacenters. These difficult physical access. After several years of work, unexpected reboot (power problems, panic, ....) on the file system with errors. Not all file system may check and fix remotely - /, / usr can not unmount at work.

This patch allows you to schedule a scan file systems at boot time, before they are mounted.
