Bug Description

There is a race between empty cache file for the mount generator and fstab which contains /boot/grub.
With zfs on root, the generator is the only solution to avoid races. However in 0.8 it misses cache invalidation (when rollbacking or booting on other datasets).

This is a workaround for the first boot with empty files to ensure we initialize it properly.
