Encryption of course is a possible impediment (I've no idea if this is handled as it's not of particular interest to me). However with that caveat, a header including direct pointers to each block of data in sequence would seem to be workable in theory without requiring knowledge of the filesystem's layout strategy, recalling that this data is being created by something that knows how it's going to be used. (I say that without having looked at the actual format.) poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
