Title:
  [18.10 FEAT] Support 4k sectors for fast clear key dm-crypt - crypttab
  part

Status in Ubuntu on IBM z Systems:
  In Progress
Status in cryptsetup package in Ubuntu:
  Fix Released
Status in systemd package in Ubuntu:
  Fix Released
Status in cryptsetup source package in Bionic:
  New
Status in systemd source package in Bionic:
  Fix Committed

Bug description:
  [Impact]

   * cryptsetup in bionic supports creating luks volumes with a non-
  standard sector-size option, and thus this option also needs to be
  used when activating the LUKS volumes. Add sector-size= option support
  to /etc/crypttab.

  [Test Case]

   * Create a plain LUKS volume with sector-size 4096
   * Specify sector-size=4096 option in /etc/crypttab
   * reload systemd, start systemd-cryptsetup at .service for that volume
   * check the journal, to ensure that `sector-size` option was recognized and is active. (i.e. there is not error messages about unrecognized option `sector-size` from systemd-cryptsetup)

  [Regression Potential]

   * This is an optional argument, not used by default. Currently custom
  sector-size crypttab does not work correctly, and thus cannot regress.

  [Other Info]
   
   * Original bug report

  Support fast clear key dm-crypt with 4k support

  Extend /etc/crypttab  to enable 4k sector support in plain mode

  The proposed enhancements are posted on github, see
