[Bug 913336] Re: grub-common recreates /etc/grub/grubenv

[Richard Laager]

My original description was wrong. This does not stop the boot. GRUB
does timeout and continue.

After more thought, I believe my two patches are the correct solution to
this problem. If we were to simply suppress the error on boot, then an
admin who wants the features provided by the grubenv file would be
thinking, "This appears to be setup correctly. The grubenv file exists.
I don't get any errors. Why doesn't this work?"

Title:
  grub-common recreates /etc/grub/grubenv

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  /etc/init.d/grub-common and /etc/pm/sleep.d/10_grub-common call grub-
  editenv to clear the recordfail setting to indicate that the system
  booted or awoke successfully. They call grub-editenv, which creates
  the grubenv file if it doesn't exist.

  If the admin has deleted the grubenv file intentionally because they
  don't want grub writing to the filesystem, this behavior is annoying.
  If the admin has deleted the file because grub does not have write
  support for the root filesystem, then this behavior breaks booting;
  someone has to hit a key on the console for the machine to boot.

  The attached patch fixes this. However, I'm not sure what is supposed
  to create /boot/grub/grubenv originally. If it's the init script, then
  some further changes will be required.
