Subject: dd - root partition security
Date: Sat, 13 Aug 2016 13:34:01 +0200

rm / # do not remove root partition
rm -f / will remove root partition

In my opinion:

dd of=/dev/sda # will destroy sda even if it is a root partition, it 
should not
dd -f of=/dev/sda # -f flag do not exists for dd, it should be added so 
it can force a write if the previous step is implemented


Please leave feedback.

Since dd is a lower level and much less widely/frequently used tool,
I don't think it's warranted.
