# This is an example script that install and configure grub after installation.

# To use it put it in your CUSTOMIZE_DIR, make it executable, and edit EXTRAPKGS

# of your $sysconfdir/default/ganeti-instance-debootstrap.

#

# Xen, for etch/lenny i386:

#   EXTRA_PKGS="linux-image-xen-686,libc6-xen"

# Xen, for etch/lenny amd64:

#   EXTRA_PKGS="linux-image-xen-amd64"

# KVM:

#   no extra packages needed besides the normal suggested ones

#

# Do not include grub in EXTRA_PKGS because it will cause error of debootstrap.
