There is a bug report about this already in the Ubuntu bug tracking system here, whih was upgraded to "critical" as result of my bug report. http://launchpad.net/bugs/420080 It should get looked at for 11.04 now and hopefully be fixed. The only thing really needed is a detection of existing LUKS headers and a strong warning that you will kill them by proceeding. For my side this closes the discussion. Any clunky cryptsetup-integrated backup is not a clean option, as "luksHeaderBackup" works just fine and avoids numerous possible problems with the other solutions proposed here. It just has to be used. Arno -- Arno Wagner, Dr. sc. techn., Dipl.
