[Bug 1580308] Re: update-initramfs cryptsetup must correctly take into account PARTLABEL inside /etc/fstab

[Thomas Mayer]

Doing updates with apt-get, I get messages like

cryptsetup: WARNING: failed to detect canonical device of /dev/sdXY

Besides the warning message, everything seems to run fine.

I'm using ubuntu 16.04 with recent updates.

Title:
  update-initramfs cryptsetup must correctly take into account PARTLABEL
  inside /etc/fstab

Status in initramfs-tools package in Ubuntu:
  New

Bug description:
  Systematically,

  -  With a /etc/fstab using UUID or LABEL, update-initramfs works
  correctly

  -  With a /etc/fstab using PARTLABEL, update-initramfs displays following error messages :
  cryptsetup: WARNING: failed to detect canonical device of PARTLABEL=Ubuntu-Gnome
  cryptsetup: WARNING: could not determine root device from /etc/fstab
  cryptsetup: WARNING: failed to detect canonical device of PARTLABEL=USR-Ubuntu

  The cryptsetup part of update-initramfs must correctly take into
  account PARTLABEL inside /etc/fstab

  Thank you in advance
