    >All sensitive data stored in /home and /var partitions will be highly secured in case someone gains physical access to your machine hard-drive.

    I’m sorry, how exactly is it gonna be secured from anyone when we’ve just configured these partitions to be mounted automatically without asking the passphrase so anyone will be able to login on our machine and read all the data from these partitions?

    • Matei Cezar says:

      That’s just a simple trick used to decrypt the partitions. I wouldn’t suggest that you should host the key on any of internal hard-disks but you can use an external drive to keep the key secure and plug the drive.

  2. Matei Cezar says:

    If you can boot-up and login to the console check if the / partition is present on fstab (i’m guessing the root partition is not encrypted). Then update the initramfs image with the command ‘update-initramfs -u’

  3. z3d0 says:

    Hi, after “update-initramfs -u -k all” the system won’t boot anymore with the error “Unable to find LVM volume hostname-vg/root”. Without that command the passphrase as still asked at boot. Do I need to add anything to /etc/fstab?
    Any other suggestion?
