Strange setup problem

[David Frascone]

I'm trying to update my grub installation on an embedded system running on 
compact flash.

So, I wget my upgrade tar archive.  It's basically the /boot/grub filesystem, 
and /grubexe (the grub executiable itself, statically linked):

wget http://somewhere/newgrub.tgz

cd /boot
rm -rf *
tar -xvzf newgrub.tgz
cp grubexe ../grub
cd ..
umount boot
sync
./grub --batch --no-floppy >/dev/null 2>/dev/null <<EOF
root (hd0,0)
setup (hd0)
quit
EOF
sync

The problem is, sometimes the above hangs works.  And, sometimes, it causes the 
box to hang at boot (at the MBR . .I get GRUB <hang> on the console.

Any ideas for automating this upgrade?

-Dave
