grubinstall is a simple program with clear documentation to take the mystery out of the GRUB boot loader. It installs GRUB in an especially simple, robust, hard-to-screw-up form: in a dedicated contiguous boot area at the beginning of the boot disk. This is in contrast to the tools in the GRUB package, which get filesystems involved.
hprofile is a simple way to manage profiles for hardware configurations, network connections, power management, usage patterns, and many other things. A profile can define alternate versions of any configuration (or other) file, anywhere in the file system, and arbitrary scripts can be run when profiles are started or stopped (e.g. to configure hardware or start/stop services). Special support is also included for 'boot' profiles, allowing you to select profiles at startup and enter different runlevels depending on which profile was selected. It's easy to use and configure, and comes with comprehensive documentation.

iPXE is a network boot firmware. It provides a full PXE implementation enhanced with additional features such as the ability to boot from a Web server using HTTP, and the ability to boot from a SAN using iSCSI, AoE, SRP, or FCoE. It supports a wide variety of network devices, including wireless and Infiniband networks. iPXE is an effective replacement for gPXE.
