lemann,

Yeppp this is what I currently do, and offers the best performance IMO compared to using something like gocryptfs in userspace on top of BTRFS. Pretty happy with it except a few small things…

It can be a bit of a faff to mount on a new machine if its file manager doesn’t support encrypted volumes natively ☹️. On your daily you can have it all sorted in your crypttab and fstab so it’s not an issue there

My main problem though is if it’s an external USB device you have encrypted with LUKS, the handles and devices stay there after an unexpected USB disconnect… so you can’t actually unmount or remount the dm-crypt device after that happens. Anytime you try, the kernel blocks you saying the device is busy - only fix i’m aware of is a reboot.

If the encryption is managed by the filesystem itself, one would probably assume this kind of mounting & unexpected disconnect scenario would be handled as gracefully as possible

lemann,

Several years ago on YouTube I was watching people rig up their own disused rail carts using battery drills, lawnmower engines and all sorts lol
