-# If this is a Jaunty machine, the fix from LP #291256 caused our
-# patch to update-grub to not work, so let's use that mechanism
-# instead.
+# Since pv_ops kernels force block device names to xvda, xvdb, etc,
+# the default root value of root=/dev/hda won't actually help us.

 #
 #

-# Since we haven't run update-grub yet, we need to generate the
-# skeleton of a Debian menu.lst so that update-grub extracts the
-# options correctly
+# To work around that, find a UUID for the swap and root partitions
+# and use that in the grub config (and also in /etc/fstab)
