Title:
  OS prober chooses /dev/sdX notation when UUIDs requested

Status in “os-prober” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: os-prober

  OS prober insists on identifying one of my installations by /dev/sdXY
  notation, even though it's told to use UUIDs.

  All the rest of them are correctly identified by UUID.

  
  Here is the grub.cfg file.
