Well, as stated, on (deeply) embedded systems overlayfs is common. You have a lowerdir with read-only files and an read-write upper dir. Of course both lower and upper directory need to be encrypted. In my case ubifs+fscrypt, sometimes also combined with an encrypted+authenticated squashfs. Thanks, //richard
