Hello!
I am setting up a new system. I would like to use Btrfs partially for learning, partially because it seems to be 'the future' and i intend to use this system for quite some time.
I have a 256 GB SSD and a 2 TB HDD. (On the SSD, i will also install Win 10, so this will be a dual boot.) I would like to encrypt my data, but keep root unencrypted, mainly for performance reasons, also because i think it is not nescessary for my security needs.
I am totally new to Btrfs. (I have used LUKS before, though.) My main question: Would the following work?
- Setting up the system on a Btrfs on the SSD
- Setting up home on a Btrfs on LUKS on the HDD
Can i integrate these two Btrfsses as one "volume" even though one is on LUKS and one is not? And: Can i still make sure that all user-data (except for temporary data) stays on the encrypted disks?
As far as i understand, this should not be a problem. Would you expect problems/drawbacks? The alternative would be full encryption, i guess. For that, i do find instructions on the net, but not for my particular layout, so i'd be grateful for comments, advise, warnings and so on.
If helpful, i can detail my current state of planning for the whole disk layout so far. I haven't worked out the fine details yet, though, because i am not sure if i am missing something that would make this approach a bad idea.
Any comments appreciated.
