One of our customers has asked us to look into possibly encrypting the entire O/S. I have been looking at truecrypt but don't see the options that some online documents show with the system --> encrypt system partition. Is this possible in CentOS 5.7 with already an existing install in place? Can someone help me out on how I convert the mounts? The only thing I see from the GUI is to format and encrypt a new partition.
I won't be the end of the world if I tell our customer only their data mount will be encrypted but I want to be sure so they don't question my response.
