I've identified dm-1 to be the luks-swap partition, and it's the only one
mounted via fstab, because / is mounted via initrd and the kernel cmdline.
So I have /dev/mapper/swap in fstab with the matching entry in /etc/crypttab,
using a random key for re-initializing the swap luks device.
As a bootloader I use syslinux.
