Hi until now I used a tool to make hidden partitions called scubed (is something like a partition tool that used cryptsetup to create the needed volumes (really old but worked fine) http://cube.dyndns.org/cgi-bin/viewvc.cgi/trunk/scubed.c?diff_format=l&sortdir=down&logsort=rev&sortby=log&view=markup&root=scubed - I get realized from this: http://code.google.com/p/cryptsetup/issues/detail?id=105 With scubed you create five cryptsetup levels in the same device and with all unlocked you assign needed blocks to each of them with scubed) I haven't get troubles with this is able for example to create read only media (dvd+-r) with multiple ciphered layers. Here is the readme (with a mini tutorial): http://cube.dyndns.org/svn/scubed/trunk/README I think this will not be compatible with --shared flag. If this is correct is there any possibility to make non-exclusive flag available if cryptsetup will not control resizing partitions if not an underlaying tool? (as this one does that use dm-linear I think?) If not at least can be enabled the non-exclusive flags to read only media? Thanks for your time. _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
