As a non-expect in cryptsetup who just wants his swap space back, let me see if I understand the problem.
Automatically formatting a swap partition is a destructive operation, so all reasonable checks should be made before doing it. It is currently not possible to positively identify a swap partition encrypted with a random key; nor is it possible to negatively identify a partition as not encrypted (with some unknown key). This gives me two ideas: 1. Create a marking for partitions to be encrypted with a random key, allowing for the positive identification above. Perhaps this should be part of LUKS. 2. If I use LUKS for all encrypted filesystems, I believe it is possible to perform the negative identification above. That is, if I don't see the LUKS header, and the partition does not have an unencrypted volume, then it is safe to destroy. So let me promise that I have no non-LUKS encrypted filesystems. It would be a shame to require extra configuration for encrypted swap with a random key, as this is a commonly recommended setup. Furthermore, it not "fundamentally dangerous"; the only reason it is dangerous today is that we don't mark partitions clearly enough, and that could change. So we should be able to find a solution. On the other hand, I'm glad you guys are so concerned with the safety of my data! Andrew -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
