[Bug 1565226] Re: update-grub overenthusiastically places root=UUID=XXX (xenial)

Your bug report indicates that you are using the grub1 package, which
has not been supported for new installs since before 14.04.  Please
upgrade to grub2 by installing the grub-pc package, and if you still
experience problems, file a bug against that package.

** Changed in: grub (Ubuntu)
       Status: New => Won't Fix

Title:
  update-grub overenthusiastically places root=UUID=XXX (xenial)

Status in grub package in Ubuntu:
  Won't Fix

Bug description:
  The xenial initramfs will not mount the root partition using the
  UUID=XXX format when the root drive is mapped (e.g., through a LVM).

  update-grub builds its menu.lst file with kernel command line parameters for root= as, e.g.,
  kernel          /vmlinuz-4.4.0-16-generic root=UUID=2dddd69e-e70b-45c2-a262-abcdabcdabcdabcd ro quiet splash 

  Solution is to change UUID to /dev/mapper format, e.g.,
  kernel          /vmlinuz-4.4.0-16-generic root=/dev/mapper/mylvm-root ro quiet splash 
  by changing the kopt line in /boot/grub/menu.lst and re-running update-grub.

  Note: tested with /etc/fstsab using /dev/mapper/ mount points.

  (Upgraded from wily -> xenial.)
