From dc5719607e68ff5519b76362ac265cf9df225cfd Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Thu, 27 Dec 2007 12:56:32 +0000 Subject: [PATCH] Fix pygrub handling of many kernels If there are a large number of kernel images configured in grub.conf there will be too many to fit in the limited size pygrub display. This patch fixes this so that the list of kernels scrolls as needed. Signed-off-by: Daniel P.
