#6 Re: How To Migrate to a full encrypted LVM system Posted by mcortese (213.70.xx.xx) on Wed 30 Jan 2008 at 15:01 Yes. You get to have 15 slots where you can store 15 different keys, and each one will be able to unlock the partition. This allows different users to boot the system without actually sharing their keys. Currently the LUKS scheme provides a method to add a new key (action luksAddKey to cryptsetup), and another method to remove and old one (action luksDelKey). Changing a key is just a matter of adding the new one and removing the old one. This may look simple in theory, but the practical use is quite clumsy because you do not have any hint on which slot is allocated to which user (except maybe searching the logs).
