Migrating from ext to BTRFS & LUKS (for encryption and snapshots)

uConsole
1

@Rex I’ve been a big fan and a user of your DragonOS (Debian Trixie version) for my CM5 uConsole and NVMe boot drive. Since I’ve been bringing it everywhere, I was hoping to harden it with an encrypted file system in case I lose it. I’ve been trying to convert my root partition in ext to BTRFS and LUKS2, so that I get encryption and snapshots. So far, it’s not working, despite updating fstab, config.txt and crypttab and updating initramfs.

Is there any way anyone can recommend that would work? Many thanks!

Unfortunately, I can’t help you directly. But perhaps you’ll find it useful to encrypt only the home directory or a separate partition, rather than the root partition. That’s what I did with my two uConsoles.

I carried out the partitioning manually before the first boot and then created a separate home/data partition. I only encrypted that one. The system itself, however, I didn’t encrypt. This allowed me to add encryption to the system from within the system itself.
