<PRE>I've been re-running /boot/grub/install.sh from within chroots for years 
with no problem.  But today when I tried doing this, I consistently got 
Error 21: no such device.  After googling a bit, I noticed that if I 
started grub in the rescue system and did &quot;grub&gt; geometry (hd0)&quot;, I got 
a correct response, but when I did the same thing from a chroot, it got 
Error 21.

If I bind-mount the rescue system's /dev to the chroot's /dev, it works 
fine.

This makes perfect sense, except for the fact that I've never had to do 
it before.  Any idea what changed ?  This has the potential to screw up 
a lot of folks who were used to the old way.

Maybe /dev/sdX entries are no longer static, and so don't exist on the 
root partition unless it is the booted system ?
