You are right about that; I just saw the sd14 on fstab, and thought it should be the same on grub.

ext4 is fully backwards compatible with ext3, obviously; otherwise 张春江 would not be able to boot his system.

Since I believed that the /boot partition and dir could differ, I thought it would be the safest route; now it doesn't really matter. But anyway, the initramfs is automatically generated by dracut; I don't see a reason to keep one if it seems to be failing, when I trivially can create a new one. I delete mine all the time.
