Hi,

I'm usually using a setup with three partitions on a disk

Partition 1:  plain ext4 boot partition mounted on  /boot
Partition 2:  luks-encrypted swap
Partition 3: luks-encrypted btrfs for /  /home ...

both mentioned in /etc/crypttab like

sda2_crypt UUID=a7976d5c-6191-436d-9cf9-2cedf17d0893 none luks,swap,discard
sda3_crypt UUID=339b9a90-8292-422d-a3cf-eeb0317e9f84 none luks,discard


With several machines I have installed 15.10 beta on and in several cases I experienced the problem that the swap is not activated at boot time and that /dev/disks/by-uuid does not contain a link to the swap partition, and the previously created luks-encrypted swap is destroyed after boot: It is not a luks partition anymore and filled with random (presumably encrypted) bytes without structure. 

I first thought that this is a problem of the setup process, and
repaired the swap manually. But then I found the partition destroyed
again. This happend several times on several machines.

I am not sure yet what exactly would destroy the partition.
