Hmm, thinking of a future swsusp2 with initrd capabilites encrption of the suspend image itself is still useful to prevent data gathering after resume. Using dm-crypt for encryption of the swap partition in this case is useful during resume so this fits nicely together. BTW: I spent my day on implementing the encryption of the suspend image and will send patches after a few more tests. -- Andreas Steinmetz SPAMmers use [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
