[Bug 497110] Re: "WARNING: found more than one resume device candidate" - concerning same partition

[Andreas Scherbaum]

This bug is still present in 11.10, and *it is* causing boot failures!
My system also hangs after entering the passphrase for the disk encryption: Both mentioned devices in the error message point, in the end, to the same device.

Title:
  "WARNING: found more than one resume device candidate" - concerning
  same partition

Status in tools for generating an initramfs:
  Invalid
Status in “cryptsetup” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: cryptsetup

  Every time I run 'apt-get upgrade' in Lucid Lynx I see the following
  message:

  cryptsetup: WARNING: found more than one resume device candidate:
                       /dev/sda5
                       UUID=51aad372-2afa-4550-928d-6387e153d80e

  That sounds pretty serious, but when I investigate the matter I find
  that /dev/sda5 and  UUID=51aad372-2afa-4550-928d-6387e153d80e are
  actually the same partition:

  ~# ls -l /dev/disk/by-uuid/51aad372-2afa-4550-928d-6387e153d80e
  lrwxrwxrwx 1 root root 10 2009-12-15 15:53 /dev/disk/by-uuid/51aad372-2afa-4550-928d-6387e153d80e -> ../../sda5

  Expected behavior: The cryptsetup configuration script should be smart
  enough to find out that the partitions are one and the same, and it
  should not worry the user with a warning.
