Can you elaborate on this a bit?  I&#x27;m definitely not an encryption expert, but I was under the impression that full disk encryption on Linux with a sufficiently long passphrase was secure.<p>I personally use cryptsetup (dm-crypt&#x2F;LUKS) on my laptop running Arch Linux just in case it were stolen.  Are you saying that bypassing the bootloader with a live USB, etc, could give an attacker access to the data stored on the encrypted drive (outside of the boot partition, of course)?  That seems like it would defeat the purpose of full disk encryption.  Note: I understand that this is assuming that the attacker does not gain access to the system while it is up and running.
