You may even have +an initrd that does your current crypto setup already. + +At this point you want to encrypt your swap, too. Still you want to +be able to suspend using swsusp. This, however, means that you +have to be able to either enter a passphrase or that you read +the key(s) from an external device like a pcmcia flash disk +or an usb stick prior to resume. So you need an initrd, that sets +up dm-crypt and then asks swsusp to resume from the encrypted +swap device. + +The most important thing is that you set up dm-crypt in such +a way that the swap device you suspend to/resume from has +always the same major/minor within the initrd as well as +within your running system. The easiest way to achieve this is +to always set up this swap device first with dmsetup, so that +it will always look like the following: + +brw------- 1 root root 254, 0 Jul 28 13:37 /dev/mapper/swap0 + +Now set up your kernel to use /dev/mapper/swap0 as the default +resume partition, so your kernel .config contains: + +CONFIG_PM_STD_PARTITION="/dev/mapper/swap0" + +Prepare your boot loader to use the initrd you will create or +modify.
