Linux Kernel Configuration
└─>File systems
└─>Overlayfs: follow redirects even if redirects are turned off
In linux kernel since version 4.2 (release Date: 2015-08-30)  
Disable this to get a possibly more secure configuration, but that
might not be backward compatible with previous kernels.

If backward compatibility is not an issue, then it is safe and
recommended to say N here.
