[Bug 1804314] Re: Wrong WARNING Option 'hash' missing in crypttab

[Steve Langasek]

Well, why are you configuring *anything* except /etc/crypttab?  It looks
to me like the error is that you've duplicated the information from
/etc/crypttab in different places on your system, but have not included
the key 'luks' line, which means the wrong entry is copied into the
initramfs because you've overridden it.

You should only ever need to configure this information in one place on
the system - /etc/crypttab.

Title:
  Wrong WARNING Option 'hash' missing in crypttab

Status in cryptsetup package in Ubuntu:
  Incomplete

Bug description:
  I have installed kubuntu 18.10 on an encrypted partition.

  I have written a /etc/crypttab
  CryptDisk UUID=c9deed35-610e-4328-b8e7-079e95d43f76 none luks,hash=sha256,tries=3

  At each boot, I get this warning "cryptsetup: WARNING: Option 'hash' missing in crypttab".
  I tried with and without the hash=sha256 but the warning does not change.
