Comment 4 for bug 1756840

"Full disk encryption" doesn't actually mean the full disk -- it means a specific block device, so you could leave your NTFS partitions alone and encrypt only your ext4 partitions (and swap partitions, if you use them).

You've got two real options:

- block device encryption such as via dm-crypt or LUKS
- fscrypt front-end to filesystem-native encryption

Probably a bug report is the wrong place to learn about the alternatives. They serve different threat models and interact with the user in different ways, and one or the other may be better integrated into other tooling.

Thanks
