Description:
GRand Unified Bootloader, version 2 (Xen host version)
GRUB is a portable, powerful bootloader. This version of GRUB is based on a cleaner design than its predecessors, and provides the following new features: . - Scripting in grub.cfg using BASH-like syntax. - Support for modern partition maps such as GPT. - Modular generation of grub.cfg via update-grub. Packages providing GRUB add-ons can plug in their own script rules and trigger updates by invoking update-grub. . This package arranges for GRUB binary images which can be used to boot a Xen guest (i.e. PV-GRUB) to be present in the control domain filesystem.
