[Bug 1569567] Re: Running update-grub on ppc64el does not update /boot/grub/grub.cfg with options from GRUB_CMDLINE_LINUX_DEFAULT

[Dave Chiluk]

Apparently update-grub was using kexec-tools.cfg, and completely
ignoring /etc/default/grub as I expected.  So that's the workaround, but
setting in /etc/default/grub should still work.

Title:
  Running update-grub on ppc64el does not update /boot/grub/grub.cfg
  with options from GRUB_CMDLINE_LINUX_DEFAULT

Status in grub2 package in Ubuntu:
  New

Bug description:
  Running update-grub on ppc64el does not update /boot/grub/grub.cfg
  with options from GRUB_CMDLINE_LINUX_DEFAULT.

  Reproducer:
  1. edit GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub .  
  2. Run update-grub
  3. check /boot/grub/grub.cfg for the correct options

  Unfortunately I've only checked this on a 14.10 ppc64el machine, so
  this needs to be verified on a 14.04 machine, but I didn't want to
  lose this bug just in case.

  It seems to only affect ppc64el hardware.

  My line looked like 
  GRUB_CMDLINE_LINUX_DEFAULT="console=hvc0 crashkernel=2G-4G:320M at 32M,4G-32G:512M at 32M,32G-64G:1024M at 32M,64G-128G:2048M at 32M,128G-:4096M at 32M"
