Title:
  [trusty] Swap partition not set up correctly

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  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 at 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 at 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
   2      512MB   1024MB  512MB   ext2
   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.
