Can we support Deniable Encryption for the entire operating system? Something that VeraCrypt does for Windows, unfortunately VeraCrypt does not support a hidden OS feature for Linux.
So the option should apply either for the home partition or the entire OS where it creates a hidden OS within the same partition or it creates a hidden home partition.
The way it would work is that the outer password would unlock the outer container, this is where a bunch of fake sensitive files will be stored, making it look like a daily operating system. Whereas the inner password would unlock the inner container of operating system or inner home partition, this is where the real files will be stored.
Having just a standard encryption is not enough as authorities can legally force the user to give up their encryption passwords, thus making standard encryption quite useless. Deniable Encryption can help circumvent this.
