[Bug 913336] [NEW] grub-common recreates /etc/grub/grubenv

[Richard Laager]

Public bug reported:

/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.
