Public bug reported:
I think I found a bug with the creation of the swap, here is what I did
sda1 was kept as EFI
sda2 created as ext2 mount to /boot
sda3 created as swap
sda4 created as btrfs
I selected "Encrypt my home"
Installation went fine.
After reboot and logon I asked myself if SWAP was encrypted as I only
selected swap, after I found out that when I create a dmcrypt volume I
could not select a random key, which I would like to have for swap.
To my satisfaction crypttab was already set up!
mfl@devore:~$ cat /etc/crypttab
cryptswap1 UUID=5300177f-d9c4-4d71-9039-b65273ce9917 /dev/urandom
swap,cipher=aes-cbc-essiv:sha256
BUT: top shows, that there is no swap enabled:

weird!

Okay, partition missing? Weird! Check parted...
mfl@devore:~$ sudo parted /dev/sda print all
Model: ATA TOSHIBA THNSNH25 (scsi)
Disk /dev/sda: 256GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 512MB 511MB fat32 boot

3 1024MB 6024MB 5000MB
4 6024MB 256GB 250GB btrfs
sda3 happens to be there, but not found by UUID with which it was set up
by the installer.
