Section Number and Name: 

Describe the issue: 
~~~~
RHEL 7 onward /etc/sysctl.conf is added in initramfs by dracut.

This changes enable systems to apply network and other configuration immediately at boot, before the actual root partitions is mounted. This is important for some environments in particular, those with root on the network.

Also this improvement can cause some un-wanted problems.
This changes get populated to initramfs once its created by dracut.
Any mistake/temporary changes can make the systems apparently un-bootable.

One of our strategic customer requested to get this behavior documented in product documentation.

Hello Maxim ,

>>Is it the same problem as in [1]? If so, is the solution [2] sufficient?

Yes both are same (even the related sfdc case is same) and the documentation looks perfect !

Thanks,
