What does the .autorelabel file do in Linux?

What does the .autorelabel file located at the file root / do in Linux?

I know its something to do with SELinux but I can't find any information as to what it actually does. I am running CentOS 6.

Thanks in advance.


Solution 1:

Next time when you will reboot the system, it will relabel the filesystem for SElinux automatically.

This usually occurs when labeling a file system for SELinux for the first time, or when switching between different types of policy, such as changing from the targeted to the strict policy.
