Hi Cassiano! You've written: "a far as I know the mapping should be recreated each time you reboot using /sbin/cryptsetup. We are using luks extension and at each reboot we need to issue cryptsetup luksOpen </dev/name> <mappername>. /etc/crypttab should make the use of this command unecessary. The passphrase will then be asked at boot time." Can you describe how to we need do that?
