With standard Dracut parameters, the crypt module automatically prompts for the password or uses key files. SEE ALSO top systemd(1), crypttab(5), systemd-cryptsetup@. This ensures the correct device will be identified and used even if the device node (eg: /dev/sda5) changes. Changes the existing UUID when used with the luksUUID command. cipher-alg Name of the cipher algorithm and key length.

The system never asks for the password. --usage Show short option help. The sda2 UUID goes to /etc/crypttab and the volume UUID (for example debian_crypt-root) goes to /etc/fstab . This article is a guide which covers the process of configuring a drive to be encrypted using LUKS and btrfs. This includes the preferred formats raw and qcow2 as well as formats that are supported for compatibility with older QEMU versions or other hypervisors.

I've even tried using LVM on top of LUKS, but that didn't change anything. 1. : git clone <your-fork-url> ubuntu-setup cd ubuntu-setup Clone or copy this repository into the live session, e. It's impossible to check any of these in your question since it's all xxx-ed out. My problem is that the current Debian stable (squeeze) uses 1. The underlying contents of the encrypted block device are arbitrary, which makes it useful for encrypting swap devices. --uuid UUID Use the provided UUID for the luksFormat command instead of generating a new one. This parameter can be specified multiple times. allow-discards=<luks uuid> Allow using of discards (TRIM) requests for LUKS partitions with the given UUID. luks Force LUKS mode. So, it would be: # cat /etc/crypttab sda2_crypt UUID=727fa348-8804-4773-ae3d-f3e176d12dac none luks # cat /etc/fstab It will map each fstab entries to its designated crypttab entries and will gracefully close all LUKS volumes when exiting the chroot.
