Why do we need encryption in the fs?
Hello, kernel newbie here,
I'm curious as to why fs'es such as ext4 need encryption in the fs, It seems to me that we've got great support for it in tools such as cryptsetup.
Point me to the fine manuals, I'm sure they exist.
Why not have encryption in the fs you ask, arguments against include the inability to use recovery tools, like photorec and that backups are more difficult this way.
Thanks, David
