Title:
  Swap not available after upgrade to 24.10

Status in cryptsetup package in Ubuntu:
  New

Bug description:
  I had fresh install of Ubuntu 24.04 with ZFS and a 8GB swap partition
  automatically made by the Ubuntu installer, as /dev/nvme0n1p3.

  I upgraded to 24.10 and the swap is not available after reboot. It
  seems swapon cannot find the encrypted partition. What went wrong
  during the upgrade?

  My /etc/fstab is unmodified since the fresh install:

  # /etc/fstab: static file system information.
  #
  # Use 'blkid' to print the universally unique identifier for a
  # device; this may be used with UUID= as a more robust way to name devices
  # that works even if disks are added and removed. See fstab(5).
  #
  # <file system> <mount point>   <type>  <options>       <dump>  <pass>
  /dev/disk/by-id/dm-uuid-CRYPT-PLAIN-dm_crypt-0 none swap sw 0 0
  # Use `zfs list` for current zfs mount info
  # bpool none defaults 0 0
  # Use `zfs list` for current zfs mount info
  # rpool none defaults 0 0
  # Use `zfs list` for current zfs mount info
  # rpool / defaults 0 0
  # Use `zfs list` for current zfs mount info
  # rpool none defaults 0 0
  # Use `zfs list` for current zfs mount info
  # rpool /root defaults 0 0
  # Use `zfs list` for current zfs mount info
  # rpool /home defaults 0 0
  # Use `zfs list` for current zfs mount info
  # bpool /boot defaults 0 0
  # /boot/efi was on /dev/nvme0n1p1 during curtin installation
  /dev/disk/by-uuid/6DA7-371B /boot/efi vfat defaults 0 1

  And my /etc/crypttab:

  dm_crypt-0 PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16 /dev/urandom
  swap,initramfs

  In /etc/crypttab I tried to replace the ID PARTUUID=d5018485-33be-40b8-80a1-9adb3c96ff16 by /dev/nvme0n1p3 but it didn't solve the problem after rebooting.
  I also tried to add these options: swap,initramfs,plain,cipher=aes-xts-plain64,size=256

  Also, I don't know if it is related but during boot, when prompted for
  the (ZFS encrypted) disk password, I have the following warning:
  cryptsetup: WARNING: Option 'size' missing in crypttab for plain dm-
  crypt mapping dm_crypt-0. Please read /usr/share/doc/cryptsetup-
  initramfs/README.initramfs.gz and add the correct 'size' option to
  your crypttab(5).
